Thermodynamics of FeSi  

Science Journals Connector (OSTI)

We show that a simple model involving two narrow (?500 K) peaks in the density of states (DOS) at the edges of a narrow (?1000 K) gap can account for the observed anomalies in the magnetic susceptibility, specific heat, thermal expansion, and elastic response of FeSi. We also show that the resistivity of FeSi, including the metal-insulator transition at about 300 K, is well described by this model. Recent band-structure calculations, although predicting the correct value for the semiconducting gap, are unable to account for the narrow peaks in the DOS needed to explain the thermodynamics. We conclude that, given the available alternatives, a Kondo insulator descriptioninvolving an extreme renormalization of the noninteracting bandsis most appropriate for FeSi.

Computed oscillator strengths and energy levels for Fe III, Fe IV, Fe V, and Fe VI with calculated wavelengths and wavelengths derived from established data  

Science Journals Connector (OSTI)

Calculated weighted oscillator strengths are tabulated for spectral lines of Fe III, Fe IV, Fe V, and Fe VI. The lines belong to transition arrays 3d6-3d54p and 3d54s-3d54p in Fe III, 3d5-3d44p and 3d44s-3d44p in Fe IV, 3d4-3d34p and 3d34s-3d34p in Fe V, and 3d3-3d24p and 3d24s-3d24p in Fe VI. For the calculations, Slater parameters are optimized on the basis of minimizing the discrepancies between observed and computed wavelengths. Configuration interaction was included among the 3dn, 3dn?14s, 3dn?24s2, 3dn?14d, and 3dn?15s even configurations and among the 3dn?14p, 3dn?24s4p, and 3dn?15p odd configurations, with 3p53dn+1 added for Fe VI. Calculated wavelengths are compared with observational data, and the compositions of energy levels are listed. This completes a series of similar computations for these complex configurations covering Fe I to Fe VI.

USING Fe-PILC as catalyst  

Science Journals Connector (OSTI)

Fe pillared clays (Fe-PILCs) were synthesized and characterized by X-ray diffraction (XRD), surface area, thermogravimetric analysis (TGA) and 57Fe Mssbauer spectroscopy. Hydrodeporphyrinization (HDP) of vanadyl octaetil porphyrine (VOOEP) and hydrodesulfurization (HDS) of thiophene were used as catalytic tests. It was demonstrated that Fe-PILCs are very active catalysts for the HDP of VOOEP. After sulfidation of the Fe-PILC, some of the iron forms a bulk pyrrhotite-type iron sulfide (Fe1?xS) phase and the Fe-PILC structure is partially destroyed by the sulfiding procedure. About half of the iron remains forming a pillar structure. Both, the segregated iron sulfide and the iron in the pillars, are active for the decomposition of the VOOEP.

Fe/Au Multilayers: Structure and Magnetoresistance  

SciTech Connect

We have measured the magnetoresistance (MR) in two sets of Fe/Au multilayers, with varying (1) Fe layer thickness, t{sub Fe} = 3-10 nm, and (2) Au layer thickness t{sub Au} = 5-15 nm, grown on Si substrates by sputtering. The multilayer interface structure and magnetic properties were studied by polarized neutron reflectometry (PNR). The study was undertaken to understand the correlation between structure of these multilayers and their magneto-transport properties.

THE SPECTRUM OF Fe II  

SciTech Connect

The spectrum of singly ionized iron (Fe II) has been recorded using high-resolution Fourier transform (FT) and grating spectroscopy over the wavelength range 900 A to 5.5 {mu}m. The spectra were observed in high-current continuous and pulsed hollow cathode discharges using FT spectrometers at the Kitt Peak National Observatory, Tucson, AZ and Imperial College, London and with the 10.7 m Normal Incidence Spectrograph at the National Institute of Standards and Technology. Roughly 12,900 lines were classified using 1027 energy levels of Fe II that were optimized to measured wavenumbers. The wavenumber uncertainties of lines in the FT spectra range from 10{sup -4} cm{sup -1} for strong lines around 4 {mu}m to 0.05 cm{sup -1} for weaker lines around 1500 A. The wavelength uncertainty of lines in the grating spectra is 0.005 A. The ionization energy of (130,655.4 {+-} 0.4) cm{sup -1} was estimated from the 3d{sup 6}({sup 5}D)5g and 3d{sup 6}({sup 5}D)6h levels.

Viscosity of liquid Fe at high pressure  

Science Journals Connector (OSTI)

Synchrotron x-ray radiography has been used to measure the viscosity of pure liquid Fe at high pressure and temperature in a large volume press. A probe sphere rising through liquid Fe at high pressure and temperature is imaged, in situ, allowing for the derivation of sample viscosity through a modified form of Stokes equation. The effect of pressure on viscosity is fit by the semi empirical framework for transport coefficients in liquid metals, providing experimental verification of constant viscosity at the pressure-dependent melting temperature of liquid Fe where no change in liquid structure occurs.

Magnetism of HgSe:Fe  

Science Journals Connector (OSTI)

The perpendicular and parallel components of the magnetization of the mixed valence system Hg1-xFexSe in the strongly dilute limit (xmagnetic fields up to 20 T. In this interesting semimagnetic semiconductor the overall magnetization is caused simultaneously by Fe3+ (Brillouin paramagnet), Fe2+ (van Vleck paramagnet), and free electrons (diamagnetic de Haas-van Alphen effect). Using a torque magnetometer the various contributions with their anisotropy are individually determined. For very low iron content (xmagnetic moment perpendicular to the magnetic field when applying the field in a nonsymmetric direction of the crystal. Using recent theoretical results on the energy-level diagram of Fe2+ in the Td symmetry of a HgSe host lattice we deduce a spin-orbit level splitting of 2 meV from our experimental data. In contrast to higher concentration samples, both the Brillouin paramagnetism of Fe3+ and the van Vleck paramagnetism of Fe2+ can be attributed to the sum from individual Fe donors with no obvious magnetic interaction between them. Finally, we also have measured de Haas-van Alphen oscillations of the conduction-band electrons with amplitudes of the same order as the paramagnetic background. From the measured crystal-field-induced anisotropy in the magnetic moment we deduce a Fermi-surface anisotropy of about 7%.

Surface magnetism of Fe(001)  

Science Journals Connector (OSTI)

Results of all-electron self-consistent semirelativistic full-potential linearized augmented-plane-wave local-density and local-spin-density studies are reported for a seven-layer Fe(001) thin film. The calculated work function for the ferromagnetic state is found to be in excellent agreement with experiment, whereas that calculated for the paramagnetic state is significantly worse (namely, 0.5 eV too large), indicating the importance of spin polarization on this electrostatic property. For both states, partial densities of states (projected by layer and by orbital angular momentum), surface states, and charge (and spin) densities are presented and their differences employed to discuss the origin of surface magnetism. No Friedel oscillation is found in the layer-by-layer charge density. The surface-layer magnetic moment is found to have been increased by 0.73?B from the center layer to 2.98?B/atom; a very small Friedel oscillation is obtained for the spin density, which indicates possible size effects in this seven-layer film. Layer-by-layer Fermi contact hyperfine fields are presented: While the core-polarization contributions are proportional to the magnetic moment, the conduction-electron contribution shows a pronounced Friedel oscillation in the central layer and, significantly, a change of sign and increase in the magnitude for the surface-layer contribution. The hyperfine field at the nucleus of the center-layer atoms is found to be in excellent agreement with experiment. The net result for the surface-layer atoms is a predicted decrease in magnitude of the total Fermi contact hyperfine field despite the large increase of their magnetic moments. The relevance of this prediction to experiment is discussed.

Electronic Properties of LiFePO4 and Li doped LiFePO4  

SciTech Connect

LiFePO{sub 4} has several potential advantages in comparison to the transition metal oxide cathode materials used in commercial lithium-ion batteries. However, its low intrinsic electronic conductivity ({approx} 10{sup -9} S/cm) is problematic. We report here a study by soft x-ray absorption/emission spectroscopy of the electronic properties of undoped LiFePO{sub 4} and Li-doped LiFePO{sub 4} in which Li{sup +} ions are substituted for Fe{sup 2+} ions in an attempt to increase the intrinsic electronic conductivity. The conductivities of the Li{sub 1+x}Fe{sub 1-x}PO{sub 4} samples were, however, essentially unchanged from that of the undoped LiFePO{sub 4}. Nonetheless, evidence for changing the electronic properties of LiFePO{sub 4} by doping with excess Li+ was observed by the XAS/XES spectroscopy. New pre-edge features the O-1s XAS spectrum of Li{sub 1.05}Fe{sub 0.95}PO4 is a direct indication that the charge compensation for substitution of Fe{sup 2+} by Li{sup +} resides in the unoccupied O-2p orbitals. A charge transfer (CT) excitation was also observed in the doped material implying that the unoccupied O-2p orbitals created by doping are strongly hybridized with unoccupied Fe-3d orbitals of neighboring sites. However, the strong covalent bonding within the (PO{sub 4}){sup 3-} anions and the large separation of the Fe cations means that the charge created by doping is not delocalized in the manner of electrons or holes in a semiconductor.

Electronic Properties of LiFePO4 and Li doped LiFePO4  

SciTech Connect

The potential use of different iron phosphates as cathodematerials in lithium-ion batteries has recently been investigated.1 Oneof the promising candidates is LiFePO4. This compound has severaladvantages in comparison to the state-of-the-art cathode material incommercial rechargeable lithium batteries. Firstly, it has a hightheoretical capacity (170 mAh/g). Secondly, it occurs as mineraltriphylite in nature and is inexpensive, thermally stable, non-toxic andnon-hygroscopic. However, its low electronic conductivity (~;10-9 S/cm)results in low power capability. There has been intense worldwideresearch activity to find methods to increase the electronic conductivityof LiFePO4, including supervalent ion doping,2 introducingnon-carbonaceous network conduction3 and carbon coating, and theoptimization of the carbon coating on LiFePO4 particle surfaces.4Recently, the Li doped LiFePO4 (Li1+xFe1-xPO4) synthesized at ARL hasyield electronic conductivity increase up to 106.5 We studied electronicstructure of LiFePO4 and Li doped LiFePO4 by synchrotron based soft X-rayemission (XES) and X-ray absorption (XAS) spectroscopies. XAS probes theunoccupied partial density of states, while XES the occupied partialdensity of states. By combining XAS and XES measurements, we obtainedinformation on band gap and orbital character of both LiFePO4 and Lidoped LiFePO4. The occupied and unoccupied oxygen partial density ofstates (DOS) of LiFePO4 and 5 percent Li doped LiFePO4 are presented inFig. 1. Our experimental results clearly indicate that LiFePO4 has wideband gap (~; 4 eV). This value is much larger than what is predicted byDFT calculation. For 5 percent Li doped LiFePO4, a new doping state wascreated closer to the Fermi level, imparting p-type conductivity,consistent with thermopower measurement. Such observation substantiatesthe suggestion that high electronic conductivity in Li1.05Fe0.95 PO4 isdue to available number of charge carriers in the material. Furthermore,Hall effect measurement on Li doped sample confirmed presence of freecharge carriers, which are responsible for the observed electronicconductivity increase in Li doped LiFePO4. There is no evidence that Fe3+valence is created by doping with excessive Li+ in Li1.05Fe0.95PO4, asshown by Fe-edge XAS. (Fig.2) Instead, charge-carrier holes resideprimarily in unoccupied O 2p states, which compensate for the chargedeficiency from Li+ substitution for Fe2+. The increased conductivity inLi1.05Fe0.95PO4 is attributed to the new charge carriers (doped holes)and the strong electron correlation between O 2p and Fe 3dstates.

FeP precipitates in hydride?vapor phase epitaxially grown InP:Fe  

Science Journals Connector (OSTI)

Fe?doped InP was grown by hydride?vapor phase epitaxy.Doping levels up to 81018 cm?3 were determined by secondary ion mass spectrometry. Additionally performed photoluminescence measurements revealed a homogeneous distribution of electrically active Fe atoms. From microstructural investigations by analytical transmission electron microscopy spherical?shaped precipitates were detected in plan?view samples. These precipitates with diameters up to 13 nm are homogeneously arranged in the epilayer. For conglomerates of precipitates a distinct enrichment with Fe and P was measured by a comparative energy dispersive x?ray analysis. The lattice plane distances of the precipitates were deduced from the electron diffraction patterns and from high?resolution electron micrographs. A comparison with calculated values for different FeP alloys indicates that the precipitates consist mainly of orthorhombic FeP.

The mechanical properties of FeAl  

SciTech Connect

Only in the last few years has progress been made in obtaining reproducible mechanical properties data for FeAl. Two sets of observations are the foundation of this progress. The first is that the large vacancy concentrations that exist in FeAl at high temperature are easily retained at low temperature and that these strongly affect the low-temperature mechanical properties. The second is that RT ductility is adversely affected by water vapor. Purpose of this paper is not to present a comprehensive overview of the mechanical properties of FeAl but rather to highlight our understanding of key phenomena and to show how an understanding of the factors which control the yield strength and fracture behavior has followed the discovery of the above two effects. 87 refs, 9 figs.

It is shown that the XAS and RIXS spectra for 122 and 1111 Fe pnictides are each qualitatively similar to Fe metal. Cluster diagonalization, multiplet, and density-functional calculations show that Coulomb correlations are much smaller than in the cuprates, highlighting the role of Fe metallicity and strong covalency in these materials.

Corrosion performance of Fe-Cr-Al and Fe aluminide alloys in complex gas environments  

SciTech Connect

Alumina-forming structural alloys can offer superior resistance to corrosion in the presence of sulfur-containing environments, which are prevalent in coal-fired fossil energy systems. Further, Fe aluminides are being developed for use as structural materials and/or cladding alloys in these systems. Extensive development has been in progress on Fe{sub 3}Al-based alloys to improve their engineering ductility. In addition, surface coatings of Fe aluminide are being developed to impart corrosion resistance to structural alloys. This paper describes results from an ongoing program that is evaluating the corrosion performance of alumina-forming structural alloys, Fe-Al and Fe aluminide bulk alloys, and Fe aluminide coatings in environments typical of coal-gasification and combustion atmospheres. Experiments were conducted at 650-1000{degrees}C in simulated oxygen/sulfur gas mixtures. Other aspects of the program are corrosion evaluation of the aluminides in the presence of HCl-containing gases. Results are used to establish threshold Al levels in the alloys for development of protective alumina scales and to determine the modes of corrosion degradation that occur in the materials when they are exposed to S/Cl-containing gaseous environments.

Al/Fe2O3 nonacomposites have explosive and high exothermic properties by thermite reaction. In this study, Al/Fe2O3 xerogel nanocomposites were prepared by solgel method and thermite reaction performance was compared with those prepared by physical mixing with sonication. Scanning electron microscopy (SEM) images of Al/Fe2O3 xerogel nanocomposites show that network structure of Fe2O3 gel covers Al nanoparticles efficiently and this indicates that improvement of thermite reaction performance due to close contact between a fuel and an oxidizer. Optimum mole ratio of Al/Fe was determined to be 2 by thermite reaction performance by differential scanning calorimetry (DSC) analysis. At Al/Fe ratio of 2, thermite reaction enthalpy of the Al/Fe2O3 xerogel nancomposite was 991.4J/g, which was higher by a factor of four than that of the nanocomposite prepared by physical mixing.

Magnetic interlayer exchange coupling in epitaxial Fe/Si/Fe(001) studied by polarized neutron reflectometry  

Science Journals Connector (OSTI)

Polarized neutron reflectometry (PNR) has been used to investigate the magnetic interlayer coupling in a MBE-grown Fe/Si/Fe(001) sandwich at room temperature and at 10 K. Both the magnitude and orientation of the magnetic moments of the Fe layers are obtained from a rigorous analysis of the PNR data. Orthogonal configurations of the Fe magnetizations were observed, providing unambiguous evidence for the presence of a biquadratic term in the exchange coupling energy. The competition between the bilinear and biquadratic exchange couplings results in distinct orthogonal and antiparallel configurations of the Fe magnetizations at room temperature. A previously unresolved magnetic configuration in the room-temperature hysteresis curve was identified by the PNR measurements as a 180 spin-flop transition. The dominant role of the biquadratic coupling at low temperatures is evident from the orthogonal configuration of the magnetizations at remanence in the measurements at T=10 K. The magnetic configurations deduced by PNR are in good agreement with those obtained by fitting the magnetic hysteresis loops using a global energy minimum calculation.

Proteome of Geobacter sulfurreducens grown with Fe(III) oxide or Fe(III) citrate as the electron acceptor.  

SciTech Connect

e(III) oxides are the most abundant source of reducible Fe(III) by microorganisms in most soils and sediments, yet few studies on the physiology of Fe(III)-reducing microorganisms during growth on Fe(III) oxide have been conducted because of the technical difficulties in working with cell growth and harvest in the presence of Fe(III) oxides. Geobacter sulfurreducens is a representative of the Geobacter species that predominate in a variety of subsurface environments in which Fe(III) oxide is important. In order to better understand the physiology of Geobacter species during growth on Fe(III) oxide, the proteome of G. sulfurreducens grown on Fe(III) oxide was compared with the proteome of cells grown with soluble Fe(III) citrate. Two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) revealed 19 proteins that were more abundant during growth on Fe(III) oxide than on soluble Fe(III). These included proteins related to protein synthesis, electron transfer and energy production, oxidative stress, protein folding, outer membrane proteins, nitrogen metabolism and hypothetical proteins. Further analysis of the proteome with the accurate mass and time (AMT) tag method revealed additional proteins associated with growth on Fe(III) oxide. These included the outer-membrane c-type cytochrome, OmcS and OmcG, which genetic studies have suggested are required for Fe(III) oxide reduction. Furthermore, several other cytochromes, as yet unstudied, were detected to be significantly up regulated during growth on Fe(III) oxide and other proteins of unknown function were more abundant during growth on Fe(III) oxide than on soluble Fe(III). PilA, the structural protein for pili, which is required for Fe(III) oxide reduction, and other pilin-associated proteins were also more abundant during growth on Fe(III) oxide. Confirmation of the differential expression of proteins known to be important in Fe(III) oxide reduction was observed, and an additional number of previously unidentified proteins were found with significant abundance in the cells grown under conditions of Fe(III) oxide reduction.

Photo- and thermal-induced antiferromagnetic interlayer coupling in Fe/(Fe-Si) superlattices  

SciTech Connect

We have grown via sputtering, Fe - iron silicide superlattices that exhibit novel thermal and photomagnetic effects. For {approximately}15 {Angstrom} nominal thickness of the silicide layer the superlattices are antiferromagnetically (AF) coupled at room temperature. Upon cooling below 100K, they gradually revert to ferromagnetic alignment, but the AF coupling is restored at low temperature by exposure to visible light off sufficient intensity (> 10 mW/mm{sup 2}). These effects are due to charge carriers in the silicide spacer layer which, when thermally or photo-generated, are capable of communicating spin information between the Fe layers.

Superconductivity in LiFeO2Fe2Se2 with anti-PbO-type spacer layers  

Science Journals Connector (OSTI)

We report on a superconductor LiFeO2Fe2Se2 with Tc?43 K, synthesized via the hydrothermal method. The anti-PbO-type spacer layer of LiFeO2 has been successfully intercalated between the anti-PbO-type FeSe layer, which results in a high-Tc superconductivity in this iron selenide material. In this material, the LiFeO2 layer is electrically neutral and does not act as an electron donor, which is remarkably different from other heavily electron-doped intercalated FeSe-derived superconductors. Based on our results and previous reports on FeSe-based superconductors, we figure out a V-shaped anion height from the Fe layer dependence of Tc in the FeSe-derived superconductors, which is in contrast to the inverse V-shaped one for the FeAs-based superconductors. Our studies expand the categories of the iron-based superconductors and open a door in the quest for potential superconductors with various spacer layers, which is helpful for the study of the underlying physics in iron-based high-Tc superconductors.

XANES study of Fe-implanted strontium titanate  

SciTech Connect

Properties of strontium titanate SrTiO{sub 3} (STO) depend to a great extent on the substitutional dopants and defects of crystal structure. The ion beam implantation method was used for doping STO (001) crystals with Fe at different doses. Implanted samples were then annealed at 350C in oxygen to induce recrystallization and remove oxygen vacancies produced during ion implantation process. The effect of Fe doping and post-implantation annealing was studied by X-ray Absorption Near Edge Spectroscopy (XANES) method and Superconducting Quantum Interference Device (SQUID). XANES allowed to monitor the change in structure of STO crystals and in the local environment of Fe following the implantation and annealing steps. SQUID measurements revealed correlation between magnetic moment and Fe implantation dose. Ferromagnetic hysteresis was observed on selected Fe-implanted STO at 5 K. The observed magnetic properties can be correlated with the several Fe oxide phases in addition to the presence of O/Ti vacancies.

Investigation of the Fe1+xSb system  

Science Journals Connector (OSTI)

X-ray diffraction, bulk magnetization, and Fe57 Mssbauer spectroscopic measurements on Fe1+xSb system for various values of x (0.14?x?0.35) are reported. The x-ray data suggest that the ASTM (American Society for Testing and Materials) data file for Fe1+xSb should be modified. The lattice Nel temperatures obtained from magnetic susceptibility and Mssbauer spectroscopic measurements are in nice agreement with each other and decrease linearly with increase in x. The Nel temperatures for the ordering of interstitial Fe atoms are higher than 60 K and increase with x. The low-temperature Mssbauer spectra have been analyzed in terms of a Lorentzian distribution of the magnetic hyperfine field at lattice sites, a low-field site, and a relatively high-field interstitial site. Also included are comments on the low magnetic moment of Fe in Fe1+xSb.

Magnetism of Mn layers on Fe(100)  

Science Journals Connector (OSTI)

The magnetic state of epitaxial overlayers of Mn grown on Fe(100) is studied using spin-polarized electron energy loss spectroscopy. Nonzero exchange asymmetries are found, demonstrating that the surface layer of the Mn overlayers has a net magnetic moment. The exchange asymmetry oscillates with a period of about two atomic layers as the Mn overlayer thickness is varied, proving that the Mn forms ferromagnetic (100) sheets and that the sheets align antiferromagnetically. The average Mn exchange splitting is found to be 2.9 eV, indicating a magnetic moment of the order 3?B.

Structure and Properties of Magnetic (Co, Fe, Fe{sub 3}C and Ni) Carbon Beads  

SciTech Connect

Nanoparticles exhibit unique physical properties due to the surface or quantum-size effects. Particular attention has been focused on magnetic nanoparticles and substantial progress has been done in this field. In this work magnetic composites, consisting of elementary metals or carbides nanocrystallites, stabilized in carbon matrix, were prepared by the procedure comprising formation of appropriate metal acrylamide complexes, followed by frontal polymerization and pyrolysis of the polymer at various temperatures. Application of frontal polymerization and further pyrolysis enables formation of composite beads consisting of Co, Fe, Fe{sub 3}C or Ni nanocrystallites stabilized in carbon matrix. It was found that the lowest pyrolysis temperature, which enables the production of metallic nanocrystallites, was 673 K for Co and Ni, and 773 K for Fe. The magnetic properties of the beads, percentage of the metallic component, their composition and shape depended on the pyrolysis temperature. Extracts on the basis of composites containing Fe{sub 3}C showed no cytotoxicity, whereas those containing Co and Ni exhibited negligible cytotoxicity up to concentrations of 6.25 mg/ml.

Advances in Fe(VI) charge storage: Part I. Primary alkaline super-iron batteries  

Science Journals Connector (OSTI)

Recent advances in super-iron batteries, based on an unusual Fe(VI) cathodic charge storage, are presented. Fe(VI) cathodes that have been demonstrated in super-iron batteries include the synthesized Fe(VI) compound with three-electron cathodic charge capacity Na2FeO4, K2FeO4, Rb2FeO4, Cs2FeO4 (alkali Fe(VI) salts), alkali earth Fe(VI) salts BaFeO4, SrFeO4, and also a transition Fe(VI) salt Ag2FeO4 which exhibits a five-electron cathodic charge storage. This paper focus on the primary alkaline Fe(VI) charge storage in aqueous electrolyte systems. Primary alkaline super-iron batteries exhibit a higher capacity than conventional alkaline batteries. Configuration optimization, enhancement and mediation of Fe(VI) cathode charge transfer of primary Fe(VI) alkaline batteries are summarized. Composite Fe(VI)/Mn(IV or VII), Fe(VI)/Ag(II) and zirconia coating stabilized Fe(VI)/Ag(II) cathode alkaline batteries are also illustrated.

Biostimulation of Iron Reduction and Subsequent Oxidation of Sediment Containing Fe-silicates and Fe-oxides: Effect of Redox Cycling on Fe(III) Bioreduction  

SciTech Connect

Microbial reduction of iron has been shown to be important in the transformation and remediation of contaminated sediments. Re-oxidation of microbially reduced iron may occur in sediments that experience oxidation-reduction cycling and can thus impact the extent of contaminant remediation. The purpose of this research was to quantify iron oxidation in a flow-through column filled with biologically-reduced sediment and to compare the iron phases in the re-oxidized sediment to both the pristine and biologically-reduced sediment. The sediment contained both Fe(III)-oxides (primarily goethite) and silicate Fe (illite/vermiculite) and was biologically reduced in phosphate buffered (PB) medium during a 497 day column experiment with acetate supplied as the electron donor. Long-term iron reduction resulted in partial reduction of silicate Fe(III) without any goethite reduction, based on Mssbauer spectroscopy measurements. This reduced sediment was treated with an oxygenated PB solution in a flow-through column resulting in the oxidation of 38% of the biogenic Fe(II). Additional batch experiments showed that the Fe(III) in the oxidized sediment was more quickly reduced compared to the pristine sediment, indicating that oxidation of the sediment not only regenerated Fe(III) but also enhanced iron reduction compared to the pristine sediment. Oxidation-reduction cycling may be a viable method to extend iron-reducing conditions during in-situ bioremediation.

Physical Properties of Intermetallic FE2VA1  

SciTech Connect

Fe{sub 2}VAl has recently been discovered to have a negative temperature coefficient of resistivity, moderately enhanced specific heat coefficient, and a large DOS at the Fermi level by photoemission. This triggered a round of heated research to understand the ground state of this material, both theoretically and experimentally. here they report a comprehensive characterization of Fe{sub 2}VAl. X-ray diffraction exhibited appreciable antisite disorder in all of our samples. FTIR spectroscopy measurements showed that the carrier density and scattering time had little sample-to-sample variation or temperature dependence for near-stoichiometric samples. FTIR and DC resistivity suggest that the transport properties of Fe{sub 2}VAl are influenced by both localized and delocalized carriers, with the former primarily responsible for the negative temperature coefficient of resistivity. Magnetization measurements reveal that near-stoichiometric samples have superparamagnetic clusters with at least two sizes of moments. X-ray photoemission from Fe core level showed localized magnetic moments on site-exchanged Fe. They conclude that in Fe{sub 2}VAl, antisite disorder causes significant modification to the semi-metallic band structure proposed by LDA calculations. With antisite disorder considered, they are now able to explain most of the physical properties of Fe{sub 2}VAl.

Tuning the magnetic and structural phase transitions of PrFeAsO via Fe/Ru spin dilution  

SciTech Connect

Neutron diffraction and muon spin relaxation measurements are used to obtain a detailed phase diagram of PrFe1{xRuxAsO. The isoelectronic substitution of Ru for Fe acts eectively as spin dilution, suppressing both the structural and magnetic phase transitions. The temperature, TS, of the tetragonal-orthorhombic structural phase transition decreases gradually as a function of x. Slightly below TS coherent precessions of the muon spin are observed corresponding to static magnetism, possibly re ecting a signicant magneto-elastic coupling in the FeAs layers. Short range order in both the Fe and Pr moments persists for higher levels of x. The static magnetic moments disappear at a concentration coincident with that expected for percolation of the J1 - J2 square lattice model.

Atom probe: a direct technique for kinetic measurements. [Fe-24Cr; Fe-32Cr; Fe-28. 5Cr-10. 6Co  

SciTech Connect

The atom probe has been used to study the phase transformations occurring within the low-temperature miscibility gaps in Fe-Cr and Fe-Cr-Co alloys. The morphology of the two-phase microstructure resulting from phase separation deep within the miscibility gaps was found to be highly interconnected and charactristic of an isotropic spinodal reaction. The characteristic dimensions of the microstructure and the changes in composition were measured as a function of aging. The coarsening of the network structures could be fitted with a power law with time exponents that were significantly less than the classical Lifshitz-Slyozov-Wagner value of one-third.

MEASUREMENT OF THE Fe VIII-Fe XVI 3-3 EMISSION IN THE EXTREME ULTRAVIOLET AND COMPARISON WITH CHIANTI  

SciTech Connect

Laboratory measurements of the n = 3 to n = 3 emission from M-shell iron ions are presented and compared to synthetic spectra from the CHIANTI spectral model. The measurements cover the range 170-290 Angstrom-Sign and are made at an electron density of about 10{sup 11} cm{sup -3}. Emission from Fe VIII through Fe XVI has been identified. Excellent agreement with CHIANTI predictions is found for most lines. Twenty weaker features are noted in the laboratory data that are either absent in CHIANTI or have recently been added and correspond to lines that have not been verified by experimental measurements. A few of these lines may have already been observed (but not yet identified) in the Sun. The features are attributed to emission from various charge states of iron, notably Fe IX and Fe XIII, and two features have been identified as transitions in Fe VIII, i.e., the 3p{sup 6}3d {sup 2}D{sub 5/2}-3p {sup 5}3d{sup 2} {sup 2}P{sub 3/2} and the 3p {sup 6}3d {sup 2}D{sub 3/2}-3p {sup 5}3d{sup 2} {sup 2}P{sub 1/2} transitions at 225.25 {+-} 0.12 and 226.35 {+-} 0.10 Angstrom-Sign , respectively. Seven lines in Fe XI, Fe XII, and Fe XIII between 200 and 205 Angstrom-Sign are noted for which the wavelengths in the CHIANTI database disagree with those in the current database of the National Institute of Standards and Technology. Our measurements of five of these lines appear to agree with the assignments used in CHIANTI.

Campbell penetration depth in Fe-based superconductors  

SciTech Connect

A 'true' critical current density, j{sub c}, as opposite to commonly measured relaxed persistent (Bean) current, j{sub B}, was extracted from the Campbell penetration depth, {lambda}{sub c}(T,H) measured in single crystals of LiFeAs, and optimally electron-doped Ba(Fe{sub 0.954}Ni{sub 0.046}){sub 2}As{sub 2} (FeNi122). In LiFeAs, the effective pinning potential is nonparabolic, which follows from the magnetic field - dependent Labusch parameter {alpha}. At the equilibrium (upon field - cooling), {alpha}(H) is non-monotonic, but it is monotonic at a finite gradient of the vortex density. This behavior leads to a faster magnetic relaxation at the lower fields and provides a natural dynamic explanation for the fishtail (second peak) effect. We also find the evidence for strong pinning at the lower fields.The inferred field dependence of the pinning potential is consistent with the evolution from strong pinning, through collective pinning, and eventually to a disordered vortex lattice. The value of j{sub c}(2 K) {approx_equal} 1.22 x 10{sup 6} A/cm{sup 2} provide an upper estimate of the current carrying capability of LiFeAs. Overall, vortex behavior of almost isotropic, fully-gapped LiFeAs is very similar to highly anisotropic d-wave cuprate superconductors, the similarity that requires further studies in order to understand unconventional superconductivity in cuprates and pnictides. In addition to LiFeAs, we also report the magnetic penetration depth in BaFe{sub 2}As{sub 2} based superconductors including irradiation of FeNi122. In unirradiated FeNi122, the maximum critical current value is, j{sub c}(2K) {approx_equal} 3.3 x 10{sup 6} A/cm{sup 2}. The magnetic-dependent feature was observed near the transition temperature in FeTe{sub 0.53}Se{sub 0.47} and irradiated FeNi122. Because of this feature, further studies are required in order to properly calibrate the Campbell penetration depth. Finally, we detected the crossing between the magnetic penetration depth and London penetration depth in optimally hold-doped Ba{sub 0.6}K{sub 0.4}Fe{sub 2}As{sub 2} (BaK122) and isovalent doped BaFe{sub 2}(As{sub 0.7}P{sub 0.3}){sub 2} (BaP122). These phenomena probably coincide with anomalous Meissner effect reported in pnicitde superconductors [Prozorov et al. (2010b)] however more studies are needed in order to clarify this.

Heterogeneous reduction of Tc(VII) by Fe(II) at the solidwater interface  

Science Journals Connector (OSTI)

Experiments were performed herein to investigate the rates and products of heterogeneous reduction of Tc(VII) by Fe(II) adsorbed to hematite and goethite, and by Fe(II) associated with a dithionitecitratebicarbonate (DCB) reduced natural phyllosilicate mixture [structural, ion-exchangeable, and edge-complexed Fe(II)] containing vermiculite, illite, and muscovite. The heterogeneous reduction of Tc(VII) by Fe(II) adsorbed to the Fe(III) oxides increased with increasing pH and was coincident with a second event of Fe 2 + (aq) adsorption. The reaction was almost instantaneous above pH 7. In contrast, the reduction rates of Tc(VII) by DCB-reduced phyllosilicates were not sensitive to pH or to added Fe 2 + (aq) that adsorbed to the clay. The reduction kinetics were orders of magnitude slower than observed for the Fe(III) oxides, and appeared to be controlled by structural Fe(II). The following affinity series for heterogeneous Tc(VII) reduction by Fe(II) was suggested by the experimental results: aqueous Fe(II)?adsorbed Fe(II) in phyllosilicates [ion-exchangeable and some edge-complexed Fe(II)]?structural Fe(II) in phyllosilicates?Fe(II) adsorbed on Fe(III) oxides. Tc-EXAFS spectroscopy revealed that the reduction products were virtually identical on hematite and goethite that were comprised primarily of sorbed octahedral TcO2 monomers and dimers with significant Fe(III) in the second coordination shell. The nature of heterogeneous Fe(III) resulting from the redox reaction was ambiguous as probed by Tc-EXAFS spectroscopy, although Mssbauer spectroscopy applied to an experiment with 56Fe-goethite with adsorbed 57Fe(II) implied that redox product Fe(III) was goethite-like. The Tc(IV) reduction product formed on the DCB-reduced phyllosilicates was different from the Fe(III) oxides, and was more similar to Tc(IV) oxyhydroxide in its second coordination shell. The heterogeneous reduction of Tc(VII) to less soluble forms by Fe(III) oxide-adsorbed Fe(II) and structural Fe(II) in phyllosilicates may be an important geochemical process that will proceed at very different rates and that will yield different surface species depending on subsurface pH and mineralogy.

Growth sequence and interface formation in the Fe/MgO/Fe(001) tunnel junction analyzed by surface x-ray diffraction  

SciTech Connect

We present a surface x-ray diffraction study of the interface geometric structure in the Fe/MgO/Fe(001) magnetic tunnel junction (MTJ). While the lower MgO/Fe(001) interface is characterized by a substoichiometric FeO{sub x} (x=0.6{+-}0.1) layer in agreement with previous studies, growth of Fe on the MgO spacer and the upper Fe/MgO interface structure strongly depends on the preparation method. If 0.4 monolayers of Fe are initially deposited in ambient oxygen atmosphere (p=10{sup -7} mbar) followed by Fe deposition under ultrahigh-vacuum (UHV) conditions, structural coherence across the trilayer junction is observed. In this case, substoichiometric FeO{sub x} layers are present at both Fe/MgO interfaces corresponding to a symmetric MTJ structure. In contrast, lattice registry is not preserved if Fe deposition is carried out solely under UHV conditions. Our results might have important implications for the preparation of magnetic tunnel junctions optimized to achieve giant tunneling-magnetoresistance amplitudes.

Electron-Ion Recombination Rate Coefficients and Photoionization Cross Sections for Astrophysically Abundant Elements. V. Relativistic calculations for Fe XXIV and Fe XXV for X-ray modeling  

E-Print Network (OSTI)

Photoionization and recombination cross sections and rate coefficients are calculated for Li-like Fe XXIV and He-like Fe XXV using the Breit-Pauli R-matrix (BPRM) method. A complete set of total and level-specific parameters is obtained to enable X-ray photoionization and spectral modeling. The ab initio calculations for the unified (e + ion) recombination rate coefficients include both the non-resonant and the resonant recombination (radiative and di-electronic recombination, RR and DR, respectively) for (e + Fe XXV) -> Fe XXIV and (e + Fe XXVI) -> Fe XXV. The level specific rates are computed for all fine structure levels up to n = 10, enabling accurate computation of recombination-cascade matrices and effective rates for the X-ray lines. The total recombination rate coefficients for both Fe XXIV and Fe XXV differ considerably, by several factors, from the sum of RR and DR rates currently used to compute ionization fractions in astrophysical models. As the photoionization/recombination calculations are carried out using an identical eigenfunction expansion, the cross sections for both processes are theoretically self-consistent; the overall uncertainty is estimated to be about 10-20%. All data for Fe XXIV and Fe XXV (and also for H-like Fe XXVI, included for completeness) are available electronically.

Formation of FePt nanoparticles by organometallic synthesis  

SciTech Connect

Our interest in determining the mechanism of FePt nanoparticle formation has led to this study of the evolution of particle size and composition during synthesis. FePt nanoparticles were prepared by the simultaneous reduction of platinum acetylacetonate and thermal decomposition of iron pentacarbonyl. During the course of the reaction, samples were removed and the particle structure, size, and composition were determined using x-ray diffraction, transmission electron microscopy (TEM), and scanning electron microscopy-energy dispersive x-ray spectrometry. Early in the reaction the particles were Pt rich (greater than 95 at. % Pt) and as the reaction proceeded the Fe content increased to the target of 50%. The particle diameter increased from 3.1 to 4.6 nm during the reaction. Energy dispersive x-ray spectrometry measurements of individual particle compositions using a high resolution TEM showed a broad distribution of particle compositions with a standard deviation greater than 15% of the average composition.

Bimetallic Fe-Ni Oxygen Carriers for Chemical Looping Combustion  

SciTech Connect

The relative abundance, low cost, and low toxicity of iron make Fe-based oxygen carriers of great interest for chemical looping combustion (CLC), an emerging technology for clean and efficient combustion of fossil and renewable fuels. However, Fe also shows much lower reactivity than other metals (such as Ni and Cu). Here, we demonstrate strong improvement of Fe-based carriers by alloying the metal phase with Ni. Through a combination of carrier synthesis and characterization with thermogravimetric and fixed-bed reactor studies, we demonstrate that the addition of Ni results in a significant enhancement in activity as well as an increase in selectivity for total oxidation. Furthermore, comparing alumina and ceria as support materials highlights the fact that reducible supports can result in a strong increase in oxygen carrier utilization.

We cannot also exclude a possibility that the increasing content of maghemite is caused by a stabilization of the spinel structure by ferrous cations, which may be generated by a reaction of iron oxide with an incompletely oxidized sucrose at higher temperature. ...

Magnetic spiral structures in La/Fe multilayers.  

SciTech Connect

The magnetic properties of La/Fe multilayers were tested by magneto-optical Kerr effect and polarized neutron reflectometry. The experiments indicated that above a layer thickness t{sub la} = 25{angstrom} the magnetic state of the virgin sample is represented by a spiral-like arrangement of magnetizations of subsequent Fe layers, whereas each Fe layer itself is ferromagnetic. Polarized neutron reflectometry shows that the helix has predominantly one chirality over the entire surface area of several cm{sup 2}. Tine magnetic spiral structure is imprinted during the growth process by rotating the sample in a small residual magnetic field. External magnetic field of 90 Oe are sufficient to erase the magnetic structure irreversibly.

Influence of Fe Contamination on the Minority Carrier Lifetime of Multi-crystalline Silicon  

Science Journals Connector (OSTI)

We investigate the influence of Fe contamination on the minority carrier lifetimes of multi-crystalline silicon. The minority carrier lifetime is measured by the microwave photoconductive decay method. The original bulk lifetime is about 30 ?s after passivation with iodine solution. After intentional Fe contamination, the bulk lifetime declines with increasing temperature. Fast cooling in air conduces to the formation of more interstitial Fe ([Fe]i). Slow cooling through the control of the furnace temperature limits the formation of more [Fe]i, but leads to the formation of precipitation. The data support the idea that the minority carrier lifetime in multi-crystalline silicon mainly depends on the distribution of Fe but not the total amount. A favorite effect of [Fe]i gettering is discovered after conventional phosphorus diffusion, and the [Fe]i concentration remaining in the silicon wafer is acceptable for solar cell applications.

Interaction and charge transfer in the iron nitride Fe4N  

Science Journals Connector (OSTI)

The linearized augmented-plane-wave method has been used to calculate the electronic bands of the cubic iron nitride Fe4N. Strong interaction between N 2p and Fe 4s orbitals of nearest Fe atoms (FeII has been revealed. This interaction leads to an increase in the N 2p population. The Fe 3d bands remain almost the same as in the pure Fe metal with negligible interaction with neighboring N orbitals. However, the occupation of the FeII 3d bands and the total number of electrons of FeII atoms increases due to less screening. This unified picture clarifies the controversy in the previous explanations of the experimental results obtained from magnetic measurements, electron diffraction, and photoelectron spectroscopy.

Catalyst characterisation of Fe-doped-titanium dioxide  

Science Journals Connector (OSTI)

Fe (5 wt. %) doped TiO2 was synthesised using a hydrothermal method. This material was characterised by X-Ray diffraction (XRD), Raman spectroscopy, scanning electron microscope (SEM) imaging, BET surface area, X-Ray photoelectron spectroscopy (XPS) and ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS). The BET surface area was 136 m/g and crystal sizes of 1.6 microns. SEM results showed crystal structures that were regular and pyramidal in shape. This catalyst only showed anatase phase. This favoured phase could be due to iron ions inserted into the TiO2 lattice and forming Ti-O-Fe bonds. It was found that doping TiO2 with 5 wt. % Fe caused a red shift in the absorption of the material to the visible light range and there was an increased absorption in the ultraviolet-visible diffuse reflectance spectroscopy, in the 450-590 nm range. These characteristics are very favourable for the use of 'free' visible light in order to activate the Fe (5 wt. %) doped TiO2 photocatalyst.

Magnetization of uncovered and V-covered ultrathin Fe(100) films on V(100)  

SciTech Connect

We used polarized neutron reflectometry (PNR) to determine the absolute magnetic moment of uncovered and V-covered Fe films in the thickness range from 0.3 to 5.5 nm. The films were prepared by molecular beam epitaxy on a V(100) buffer layer grown on a MgO(100) crystal. The magnetic moment shows a linear dependence on the Fe film thickness with a reduction (compared to the Fe bulk value) of the magnetic moment equivalent to 0.1 nm bulk Fe for the V-covered films and a reduction equivalent to 0.03 nm bulk Fe for the uncovered Fe films. For the case of the V/Fe/V samples we observe a much smaller reduction of the magnetic moment than reported for experiments on Fe/V multilayers. As theoretical calculations show a strong decrease of the magnetic moment for an interface alloy we conclude that the larger reduction of the magnetization in Fe/V multilayers is due to an increase in interface roughness with increasing film thickness. For the uncovered Fe(100) films we find a much smaller reduction of the magnetic moment than in earlier in situ PNR experiments on V(110)/Fe(110) where we observed a reduction equivalent to 0.4 nm bulk Fe.

Complex magnetic behavior of the sawtooth Fe chains in Rb2Fe2O(AsO4)2  

SciTech Connect

Results of magnetic eld and temperature dependent neutron diraction and magnetization mea- surements on oxy-arsenate Rb2Fe2O(AsO4)2 are reported. The crystal structure of this compound contains pseudo-one-dimensional [Fe2O6] sawtooth-like chains, formed by corner sharing isosce- les triangles of Fe3+ ions occupying two nonequivalent crystallographic sites. The chains extend innitely along the crystallographic b-axis and are structurally conned from one another via dia- magnetic (AsO4)3- units along the a-axis, and Rb+ cations along the c-axis direction. Neutron diraction measurements indicate the onset of a long range antiferromagnetic order below approxi- mately 25 K. The magnetic structure consists of ferrimagnetic chains which are antiferromagnetically coupled with each other. Within each chain, one of the two Fe sites carries a moment which lies along the b-axis, while the second site bears a canted moment in the opposite direction. Exter- nally applied magnetic eld induces a transition to a ferrimagnetic state, in which the coupling between the sawtooth chains becomes ferromagnetic. Magnetization measurements performed on optically-aligned single crystals reveal evidence for an uncompensated magnetization at low mag- netic elds that could emerge from to a phase-segregated state with ferrimagnetic inclusions or from antiferromagnetic domain walls. The observed magnetic states and the competition between them is expected to arise from strongly frustrated interactions within the sawtooth chains and relatively weak coupling between them.

A synthesis of LiFePO 4 starting from FePO 4 under reducing atmosphere  

Science Journals Connector (OSTI)

A fast and easy way to produce LiFePO 4 starting from FePO 4 used as iron and phosphorus source is proposed. 5% hydrogen is employed as a reducing agent and various compounds containing lithium as lithiation agents. The selected lithiation agents included: LiCl CH 3 COOLi LiOH Li 2 S LiH and Li 2 CO 3 . Solid state synthesis is used for the LiFePO 4 preparation and the so obtained materials are structurally characterized by XRD. The materials are used to fabricate composite electrode and their specific capacity is evaluated by low rate galvanostatic charge/discharge cycles (C/10 rate). Among the various lithium salts the acetate give rise to the LiFePO 4 with the best electrochemical performance. The morphology of this material is further investigated by SEM microscopy and the specific capacity is evaluated as a function of the discharge rate and the cycle number.

The importance of holes in aluminium tris-8-hydroxyquinoline (Alq{sub 3}) devices with Fe and NiFe contacts  

SciTech Connect

To study the dominant charge carrier polarity in aluminium tris-8-hydroxyquinoline (Alq{sub 3}) based spin valves, single Alq{sub 3} layer devices with NiFe, ITO, Fe, and aluminium electrodes were fabricated and characterised by Time of Flight (ToF) and Dark Injection (DI) techniques, yielding a lower hole mobility compared to electron mobility. We compare the mobility measured by DI for the dominant carrier injected from NiFe and Fe electrodes into Alq{sub 3}, to that of holes measured by ToF. This comparison leads us to conclude that the dominant charge carriers in Alq{sub 3} based spin valves with NiFe or Fe electrodes are holes.

Synthesis of Fe-zeolites and Fe-PILC samples and their activity in wet hydrogen peroxide oxidation of p-coumaric acid  

Science Journals Connector (OSTI)

The catalytic wet hydrogen peroxide oxidation of p-coumaric acid was investigated over various Fe-ZSM-5, Fe-BEA and Fe-PILC samples. The catalysts differing in the amount of iron were prepared by the solid state ion exchange method and were caracterized by XRD, BET surface area and Chemical analysis. The oxidation reaction was carried out in a batch reactor at 70C and atmospheric pressure. A great interest has been focused on the leaching-off of iron. Fe-BEA catalysts were found more effective than Fe-ZSM-5 and Fe-PILC samples. At optimal condition, a solution containing 500 ppm of p-coumaric acid, 10?2M of H2O2 and 0.5 g/l of catalyst was degraded in less than 2h with a significant total organic carbon (TOC) removal. Characterization data were correlated with the activity results.

XAS Characterization of a Nitridoiron(IV) Complex with a Very Short Fe-N Bond

Modified magnetism within the coherence volume of superconducting FeSeTe  

SciTech Connect

Neutron Scattering is used to probe magnetic interactions as superconductivity develops in opti- mally doped Fe_(1+ )Se_xTe_(1 x). Applying the first moment sum-rule to comprehensive neutron scatter- ing data, we extract the change in magnetic exchange energy [J_(R-R ) S_R S_R ] in the superconducting state referenced to the normal state. Oscillatory changes are observed for Fe-Fe displacements | R| < , where = 1.3(1) nm is the superconducting coherence length. Dominated by a large reduction in the second nearest neighbor exchange energy (-1.2(2) meV/Fe), the overall reduction in magnetic interaction energy is Hmag = 0.31(9) meV/Fe. Comparison to the superconducting condensation energy E_sc = 0.013(1) meV/Fe, which we extract from specific heat data, suggests the modified magnetism we probe drives superconductivity in Fe_(1+ )Se_xTe_(1 x)

Nd1+?Fe4B4: A composition-modulated compound with incommensurate composite crystal structure  

Science Journals Connector (OSTI)

Nd1+?Fe4B4 crystallizes with the tetragonal Sm1+?Fe4B4 structure type. It is characterized by two interpenetrating metal substructures with incommensurate translation periods, cNd and cFe. The structure is approximated using a superstructure model of composition Nd19(Fe4B4)17 with c?19cNd?17cFe=66.2(1) A?, and refined from single-crystal x-ray data to a consistency index of R=0.12 (2800 contributing reflections, 139 refined parameters). The results reveal rotational and displacive modulations of the Fe tetrahedra chains, Nd atom strings, and B atom pairs. Their periods can be expressed by Lrot=2Ldis=1/(1/crNd-1/cFe). High-resolution electron microscopy reveals 17-A?-spaced Moir-type fringes, but no commensurately spaced structure segments.

Lattice and magnetic structures of PrFeAsO, PrFeAsO0.85F0.15, and PrFeAsO0.85  

SciTech Connect

We use powder neutron diffraction to study the spin and lattice structures of polycrystalline samples of nonsuperconducting PrFeAsO and superconducting PrFeAsO0.85F0.15 and PrFeAsO0.85. We find that PrFeAsO exhibits abrupt structural phase transitions at 153 K followed by static long-range antiferromagnetic order at 127 K. Both the structural distortion and magnetic order are similar to other rare-earth oxypnictides. Electron doping the system with either fluorine or oxygen deficiency suppresses the structural distortion and static long-range antiferromagnetic order, therefore placing these materials into the same class of FeAs-based superconductors.

Effect of tungsten addition on the toughness and hardness of Fe{sub 2}B in wear-resistant Fe-B-C cast alloy  

SciTech Connect

The effects of tungsten additions of 0%, 1.12%, 2.04%, and 3.17% (in wt.%) on the morphology, fracture toughness and micro-hardness of Fe{sub 2}B in Fe-B-C cast alloy were investigated. The results indicate that, with the increase of tungsten addition, the morphology and distribution of Fe{sub 2}B have no change and a new W-containing phase, except the (Fe, W){sub 2}B with a certain tungsten solution, does not form, and that the fracture toughness of Fe{sub 2}B increases first and then decreases, while the hardness increases first and then has a little change. Compared with the fracture toughness (3.8 MPa{center_dot}m{sup 1/2}) of Fe{sub 2}B without tungsten addition, the toughness at 2.04 wt.% tungsten can be improved by about above 80% and achieves about 6.9 MPa{center_dot}m{sup 1/2}, and variation characteristics of hardness and toughness of Fe{sub 2}B were also testified by viewing the indentation marks and cracks on the Fe{sub 2}B, respectively. - Highlights: Black-Right-Pointing-Pointer Poor toughness of Fe2B decreases obviously the wear resistance of the alloy. Black-Right-Pointing-Pointer As W content increases, Fe2B's toughness increases first and then decreases. Black-Right-Pointing-Pointer As W content increases, Fe2B's hardness first increases and then has little change. Black-Right-Pointing-Pointer The toughness at 2.04 % W can be improved by above 80% more than that at 0% W.

AlN/Fe/AlN nanostructures for magnetooptic magnetometry  

SciTech Connect

AlN/Fe/AlN/Cu nanostructures with ultrathin Fe grown by sputtering on Si substrates are evaluated as probes for magnetooptical (MO) mapping of weak currents. They are considered for a laser wavelength of ??=?410?nm (3.02?eV) and operate at oblique light incidence angles, ?{sup (0)}, to enable detection of both in-plane and out-of-plane magnetization. Their performance is evaluated in terms of MO reflected wave electric field amplitudes. The maximal MO amplitudes in AlN/Fe/AlN/Cu are achieved by a proper choice of layer thicknesses. The nanostructures were characterized by MO polar Kerr effect at ?{sup (0)}???5 and longitudinal Kerr effect spectra (?{sup (0)}?=?45) at photon energies between 1 and 5?eV. The nominal profiles were refined using a model-based analysis of the spectra. Closed form analytical expressions are provided, which are useful in the search for maximal MO amplitudes.

Ferromagnetism at the interfaces of antiferromagnetic FeRh epilayers  

SciTech Connect

The nanoscale magnetic structure of FeRh epilayers has been studied by polarized neutron reflectometry. Epitaxial films with a nominal thickness of 500 {angstrom} were grown on MgO (001) substrates via molecular-beam epitaxy and capped with 20 {angstrom} of MgO. The FeRh films show a clear transition from the antiferromagnetic (AF) state to the ferromagnetic (FM) state with increasing temperature. Surprisingly the films possess a FM moment even at a temperature 80 K below the AF-FM transition temperature of the film. We have quantified the magnitude and spatial extent of this FM moment, which is confined to within {approx}60-80 {angstrom} of the FeRh near the top and bottom interfaces. These interfacial FM layers account for the unusual effects previously observed in films with thickness <100 {angstrom}. Given the delicate energy balance between the AF and FM ground states we suggest a metastable FM state resides near to the interface within an AF matrix. The length scale over which the FM region resides is consistent with the strained regions of the film.

Tunneling conductance studies in the ion-beam sputtered CoFe/Mg/MgO/NiFe magnetic tunnel junctions  

SciTech Connect

Magnetic tunnel junctions consisting of CoFe(10 nm)/Mg(1 nm)/MgO(3.5 nm)/NiFe(10 nm) are grown at room temperature using dual ion beam sputtering via in-situ shadow masking. The effective barrier thickness and average barrier height are estimated to be 3.5 nm (2.9 nm) and 0.69 eV (1.09 eV) at 290 K (70 K), respectively. The tunnel magnetoresistance value of 0.2 % and 2.3 % was observed at 290 K and 60 K, respectively. The temperature dependence of tunneling conductance revealed the presence of localized states present within the forbidden gap of the MgO barrier leading to finite inelastic spin independent tunneling contributions, which degrade the TMR value.

Nano and picosecond magnetization dynamics of weakly coupled CoFe/Cr/NiFe trilayers studied by a multitechnique approach  

Science Journals Connector (OSTI)

We present results on the magnetization dynamics in heterostructures of the CoFe/Cr/NiFe type. We have employed a combination of different layer-selective methods covering a broad range from quasistatic hysteresis measurements by x-ray magnetic circular dichroism (XMCD), over time-resolved photoemission electron microscopy (PEEM) at subnanosecond timescales to high-frequency ferromagnetic resonance (FMR) experiments. With increasing driving frequency, we found a different influence of the coupling between the two ferromagnetic layers on the dynamic behavior. Employing the spatial resolution of the PEEM method, we have been able to discern various dynamic responses in different regions of the sample that could be attributed to magnetodynamic processes with a different degree of coupling. In conjunction with the complementary FMR and XMCD measurements, we attribute the inhomogeneous influence of interlayer coupling to a shift from domain-wall-motion-dominated dynamics at low frequencies to precession-dominated dynamics at higher frequencies.

Structural Investigation of the (010) Surface of the Al13Fe4 Catalyst  

Science Journals Connector (OSTI)

We have investigated the structure of the Al13Fe4(010) surface using both experimental and abinitio computational methods. The results indicate that the topmost surface layers correspond to incomplete puckered (P) planes present in the bulk crystal structure. The main building block of the corrugated termination consists of two adjacent pentagons of Al atoms, each centered by a protruding Fe atom. These motifs are interconnected via additional Al atoms referred to as glue atoms which partially desorb above 873K. The surface structure of lower atomic density compared to the bulk P plane is explained by a strong Fe-Al-Fe covalent polar interaction that preserves intact clusters at the surface. The proposed surface model with identified Fe-containing atomic ensembles could explain the Al13Fe4 catalytic properties recently reported in line with the site-isolation concept [M. Armbrster et al., Nat. Mater. 11, 690 (2012)].

Search for supernova-produced 60Fe in a marine sediment  

E-Print Network (OSTI)

An 60Fe peak in a deep-sea FeMn crust has been interpreted as due to the signature left by the ejecta of a supernova explosion close to the solar system 2.8 +/- 0.4 Myr ago [Knie et al., Phys. Rev. Lett. 93, 171103 (2004)]. To confirm this interpretation with better time resolution and obtain a more direct flux estimate, we measured 60Fe concentrations along a dated marine sediment. We find no 60Fe peak at the expected level from 1.7 to 3.2 Myr ago. However, applying the same chemistry used for the sediment, we confirm the 60Fe signal in the FeMn crust. The cause of the discrepancy is discussed.

Magnetism of NiMn2O4-Fe3O4 spinel interfaces  

SciTech Connect

We investigate the magnetic properties of the isostructural spinel-spinel interface of NiMn{sub 2}O{sub 4}(NMO)-Fe{sub 3}O{sub 4}. Although the magnetic transition temperature of the NMO film is preserved, both bulk and interface sensitive measurements demonstrate that the interface exhibits strong interfacial magnetic coupling up to room temperature. While NMO thin films have a ferrimagnetic transition temperature of 60 K, both NiFe{sub 2}O{sub 4} and MnFe{sub 2}O{sub 4} are ferrimagnetic at room temperature. Our experimental results suggest that these magnetic properties arise from a thin interdiffused region of (Fe,Mn,Ni){sub 3}O{sub 4} at the interface, leading to Mn and Ni magnetic properties similar to those of MnFe{sub 2}O{sub 4} and NiFe{sub 2}O{sub 4}.

Strategy I responses to Fe-deficiency of two Citrus rootstocks differing in their tolerance to iron chlorosis  

Science Journals Connector (OSTI)

The expression of iron (Fe) acquisition-related genes in roots was studied in roots of two different citrus seedlings, namely, Carrizo citrange (CC, Fe chlorosis-sensitive) and Cleopatra mandarin (CM, Fe chlorosis-tolerant), growing either with (control) or without (?Fe) Fe in the nutrient solution. Fe-deficiency increased expression of the gene HA1 coding for proton-ATPase (H+-ATPase) enzyme in both genotypes, although no differences were observed between treatments among rootstocks. Furthermore, while the gene expression levels of FRO2 which encodes the Ferric Chelate Reductase (FC-R) enzyme, increased under ?Fe condition in both genotypes, CM always recorded the highest activity. CC showed the greatest induction of genes IRT1 and IRT2 encoding two iron transporters, however only IRT1 was significantly induced by Fe starvation. Analysis of the enzymatic activities (H+-ATPase and FC-R) regulated by the aforementioned genes confirmed these results. Thus, in agreement with the acidification pattern registered, H+-ATPase activities were higher in ?Fe plants than in controls, although no significant differences were detected between each treatment among rootstocks. Fe starvation also induced FC-R activity; however, this was greater in CM than in CC roots. Interestingly, root 57Fe uptake rates from 57Fe-EDDHA solutions were increased by Fe-deficiency, especially in the CM genotype, and CM accumulated a much larger Fe pool in the root apoplast than CC. Taken together, the main trait determining Fe-chlorosis tolerance among these genotypes is the ability to boost Fe3+ reduction in response to Fe-deficiency through enhanced FRO2 gene expression. Moreover, Fe chlorosis resistance in these plants could be related to the amount of Fe stored in the root apoplast.

The impact of alpha/Fe enhanced stellar evolutionary tracks on the ages of elliptical galaxies  

E-Print Network (OSTI)

We complement our study of alpha/Fe enhanced stellar population models of Lick absorption indices (Thomas et al. 2003) by comparing two sets of alpha/Fe enhanced models. In both models the impact on Lick indices due to alpha/Fe enhancement is accounted for through a modification of the stellar absorption line-strengths using the response functions of Tripicco & Bell (1995). One set of models, however, uses solar-scaled, the other alpha/Fe enhanced stellar evolutionary tracks. Since the alpha/Fe enhanced tracks are hotter than the solar-scaled ones (Salasnich et al. 2000), the correspondent stellar population models have slightly weaker metallic indices (i.e. Mgb, etc.) and stronger Balmer line indices (Hbeta) (Maraston et al 2003). Here we explore quantitatively the impact of this effect on the alpha/Fe ratios, metallicities and ages that are derived for elliptical galaxies. We find that the modest decrease of the metallic indices Mgb and balance each other, such that fully consistent alpha/Fe ratios are derived for stellar systems using alpha/Fe enhanced models with either solar-scaled or alpha/Fe enhanced stellar tracks. The decrease of the metallic indices and the increase of Hbeta conspire in a way that also consistent metallicities are obtained. The derived ages, instead, are significantly different. The inclusion of alpha/Fe enhanced stellar tracks leads to the derivation of ages as high as 30 Gyr for elliptical galaxies. For the same objects, ages not older than 15 Gyr are obtained, if alpha/Fe enhanced models using solar-scaled tracks are adopted. This may indicate that current stellar evolutionary models overestimate the bluing of stellar evolutionary tracks due to alpha/Fe enhanced chemical mixtures at super-solar metallicities.

Controlling ferromagnetism of (In,Fe)As semiconductors by electron doping  

SciTech Connect

Based on experimental results, using the Korringa-Kohn-Rostoker coherent potential approximation (KKR-CPA) method and Monte Carlo simulation, we study the mechanism of ferromagnetic behavior of (In,Fe)As. We show that with doped Be atoms occupying in interstitial sites, chemical pair interactions between atoms and magnetic exchange interactions between Fe atoms change due to electron concentration. Therefore, by controlling the doping process, magnetic behavior of (In,Fe)As is controlled and ferromagnetism is observed in this semiconductor.

Improved oxidation sulfidation resistance of Fe-Cr-Ni alloys  

DOE Patents (OSTI)

High temperature resistance of Fe-Cr-Ni alloy compositions to oxidative and/or sulfidative conditions is provided by the incorporation of about 1 to 8 wt % of Zr or Nb and results in a two-phase composition having an alloy matrix as the first phase and a fine grained intermetallic composition as the second phase. The presence and location of the intermetallic composition between grains of the matrix provides mechanical strength, enhanced surface scale adhesion, and resistance to corrosive attack between grains of the alloy matrix at temperatures of 500 to 1000/sup 0/C.

Inelastic scattering of fast neutrons from $^{56}$Fe was studied at the photoneutron source nELBE. The neutron energies were determined on the basis of a timeof- flight measurement. Gamma-ray spectra were measured with a high-purity germanium detector. The total scattering cross sections deduced from the present experiment in an energy range from 0.8 to 9.6 MeV agree within 15% with earlier data and with predictions of the statistical-reaction code Talys.

Balmer Absorption Lines in FeLoBALs  

E-Print Network (OSTI)

We discovered non-stellar Balmer absorption lines in two many-narrow-trough FeLoBALs (mntBALs) by the near-infrared spectroscopy with Subaru/CISCO. Presence of the non-stellar Balmer absorption lines is known to date only in the Seyfert galaxy NGC 4151, thus our discovery is the first cases for quasars. Since all known active galactic nuclei with Balmer absorption lines share characteristics, it is suggested that there is a population of BAL quasars which have unique structures at their nuclei or unique evolutionary phase.

Magnetic structures and interplay between rare-earth Ce and Fe magnetism in single-crystal CeFeAsO  

SciTech Connect

Neutron and synchrotron resonant x-ray magnetic scattering (RXMS) complemented by heat capacity and resistivity measurements reveal the evolution of the magnetic structures of Fe and Ce sublattices in a CeFeAsO single crystal. The RXMS of magnetic reflections at the Ce LII edge shows a magnetic transition that is specific to the Ce antiferromagnetic long-range ordering at TCe? 4 K with short-range Ce ordering above TCe, whereas neutron diffraction measurements of a few magnetic reflections indicate a transition at T?? 12 K with an unusual order parameter. Detailed order-parameter measurements on several magnetic reflections by neutrons show a weak anomaly at 4 K that we associate with the Ce ordering. The successive transitions at TCe and T? can also be clearly identified by two anomalies in heat capacity and resistivity measurements. The higher transition temperature at T?? 12 K is mainly ascribed to Fe spin reorientation transition, below which Fe spins rotate uniformly and gradually in the ab plane. The Fe spin reorientation transition and short-range Ce ordering above TCe reflect the strong Fe-Ce couplings prior to long-range ordering of the Ce. The evolution of the intricate magnetic structures in CeFeAsO going through T? and TCe is proposed.

Fe and Al Abundances for 180 Red Giants in the Globular Cluster Omega Centauri (NGC 5139)  

E-Print Network (OSTI)

We present radial velocities, Fe, and Al abundances for 180 red giant branch (RGB) stars in the Galactic globular cluster Omega Centauri ($\\omega$ Cen). The majority of our data lie in the range 11.0$Al/Fe] ratios exhibit large star--to--star scatter for all populations, with the more than 1.0 dex range of [Al/Fe] decreasing for stars more metal--rich than [Fe/H]$\\sim$--1.4. The minimum [Al/Fe] abundance observed for all metallicity populations is [Al/Fe]$\\sim$+0.15. The maximum abundance of log $\\epsilon$(Al) is reached for stars with [Fe/H]$\\sim$--1.4 and does not increase further with stellar metallicity. We interpret these results as evidence for type II SNe providing the minimum [Al/Fe] ratio and a mass spectrum of intermediate mass asymptotic giant branch stars causing the majority of the [Al/Fe] scatter. These results seem to fit in the adopted scheme that star formation occurred in $\\omega$ Cen over $>$1 Gyr.

Proton spectroscopy of 48Ni, 46Fe, and 44Cr  

E-Print Network (OSTI)

Results of decay spectroscopy on nuclei in vicinity of the doubly magic 48Ni are presented. The measurements were performed with a Time Projection Chamber with optical readout which records tracks of ions and protons in the gaseous volume. Six decays of 48Ni including four events of two-proton ground-state radioactivity were recorded. An advanced reconstruction procedure yielded the 2p decay energy for 48Ni of Q2p = 1.29(4) MeV. In addition, the energy spectra of \\b{eta}-delayed protons emitted in the decays of 44Cr and 46Fe, as well as half-lives and branching ratios were determined. The results were found to be consistent with the previous measurements made with Si detectors. A new proton line in the decay of 44Cr corresponding to the decay energy of 760 keV is reported. The first evidence for the \\b{eta}2p decay of 46 Fe, based on one clear event, is shown.

Interdiffusion Behavior of Aluminide Coatings on Fe-Base Alloys  

SciTech Connect

One of the potential degradation modes of oxidation-resistant iron aluminide coatings is the loss of Al from the coatings into Fe-base substrate alloys that typically contain no Al. To address this issue, interdiffusion between aluminide coatings and steel substrates was studied for times up to 10,000 h in the temperature range of 500-800 C. Coatings were synthesized in a laboratory chemical vapor deposition (CVD) reactor on representative commercial ferritic alloy Fe-9Cr-1Mo and type 304L austenitic stainless steel. The microstructural and compositional changes after diffusion anneals were examined in detail. An initial attempt to model the interdiffusion behavior was carried out by applying an existing software program COSIM (coating oxidation and substrate interdiffusion model). Complementary work was conducted using a simple mathematic model developed by Heckel et al. Reasonable agreement was observed between the simulated and experimental composition profiles for the aluminide coatings on ferritic alloys. Model results were then applied to predict coating lifetime.

Band-theoretical investigation of the magneto-optical Kerr effect in Fe and Co multilayers  

Science Journals Connector (OSTI)

A band theory of the magneto-optical (MO) properties of solids, based on the first-principles spin-polarized, relativistic linear muffin-tin orbital method, is described. Two expressions of the relativistic electron-photon-interaction matrix elements are implemented and their accuracies are investigated. It is found that the spin-polarized, relativistic band theory, together with the expression of the photon-absorption matrix elements, is able to give reliable optical conductivity and MO Kerr rotation spectra of bcc Fe that agree well with both experiments and recent calculations using a different method. The MO properties of several Fe and Co multilayers [Fe(Co)2Cu6 fcc-(001), FeCu(Ag)5 fcc-(001), bcc-Fe/fcc-Ag5 (001), bcc-Fen/fcc-Au5 (001) (n=1,3), Co2Pd4 fcc-(111), and Co2Ptm fcc-(111) (m=1,4,7)] are then investigated theoretically. The calculated MO Kerr effect in all the multilayers except Co2Pt1 fcc-(111) is not larger than in bulk Fe and Co. Nevertheless, the results suggest that materials with larger Kerr rotations can be achieved by making Fe (Co) superlattices with ultrathin layers (few monolayers thick) of heavy elements possessing a partially filled d band (e.g., Pt and Os).Kerr rotation spectra for Fe(Co)/Cu(Ag, Au, Pd, Pt) bilayers [i.e., a thin layer of Fe (Co) on the Cu (Ag, Au, Pd, Pt) substrate] are also obtained from the calculated optical conductivity tensors of Fe, Co, Cu, Ag, Au, Pd, and Pt. It is found that the MO Kerr effect in the Fe (Co)/noble-metal bilayers is considerably enhanced near the plasma edge of the substrate. This indicates that one can obtain good MO materials by fabricating Fe (Co) bilayers using nonmagnetic metals with a sharp plasma edge (e.g., Ag and Al) as substrates. Calculated Kerr rotation spectra of the Fe and Co multilayers as well as bilayers are in satisfactory agreement with available experiments. The spin and orbital magnetic moments in the Fe and Co multilayers are also calculated, and possible correlations between these and MO properties of the Fe and Co multilayers are discussed.

The powders were pressed into pellets, which were sintered into ceramics at 800 {sup o}C for 1 h. The morphology and structure have been determined by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). Polarization was observed in Pb{sub 2}Fe{sub 2}O{sub 5} ceramics at room temperature, exhibiting a clear ferroelectric hysteresis loop. The remanent polarization of Pb{sub 2}Fe{sub 2}O{sub 5} ceramic is estimated to be Pr {approx} 0.22 {mu}C/cm{sup 2}. The origin of the polarization may be attributed to the off-centers of shifted Pb{sup 2+} ions as well as the FeO{sub 6} octahedra in the perovskite-based structure of Pb{sub 2}Fe{sub 2}O{sub 5}. Magnetic hysteresis loop was also observed at room temperature. The Pb{sub 2}Fe{sub 2}O{sub 5} ceramic shows coexistence of ferroelectricity and ferromagnetism. It provides a new field of research for complex oxides with multiferroic properties.

Si and Fe depletion in Galactic star-forming regions observed by the Spitzer Space Telescope  

E-Print Network (OSTI)

We report the results of the mid-infrared spectroscopy of 14 Galactic star-forming regions with the high-resolution modules of the Infrared Spectrograph (IRS) on board the Spitzer Space Telescope. We detected [SiII] 35um, [FeII] 26um, and [FeIII] 23um as well as [SIII] 33um and H2 S(0) 28um emission lines. Using the intensity of [NII] 122um or 205um and [OI] 146um or 63um reported by previous observations in four regions, we derived the ionic abundance Si+/N+ and Fe+/N+ in the ionized gas and Si+/O0 and Fe+/O0 in the photodissociation gas. For all the targets, we derived the ionic abundance of Si+/S2+ and Fe2+/S2+ for the ionized gas. Based on photodissociation and HII region models the gas-phase Si and Fe abundance are suggested to be 3-100% and solar abundance, respectively, for the ionized gas and 16-100% and 2-22% of the solar abundance, respectively, for the photodissociation region gas. Since the [FeII] 26um and [FeIII] 23um emissions are weak, the high sensitivity of the IRS enables to derive the gas-phase Fe abundance widely in star-forming regions. The derived gas-phase Si abundance is much larger than that in cool interstellar clouds and that of Fe. The present study indicates that 3-100% of Si atoms and <22% of Fe atoms are included in dust grains which are destroyed easily in HII regions, probably by the UV radiation. We discuss possible mechanisms to account for the observed trend; mantles which are photodesorbed by UV photons, organometallic complexes, or small grains.

Magnetization dynamics and interface studies in ion-beam sputtered Si/CoFeB(8)/MgO(4)/CoFeB(8)/Ta(5) structures  

SciTech Connect

The interface roughness, Boron distribution in bulk CoFeB and at interface, Gilbert damping constant (?), and inhomogeneous broadening in ion-beam sputtered Si/CoFeB(8)/MgO(4)/CoFeB(8)/Ta(5) structures are found to be sensitive to the MgO growth process. The ion-assist and reactive growth processes that result in sharper interfaces of width ?0.5?nm lead to smaller ? of 0.0050??0.0003 and 0.0060??0.0002 and inhomogeneous broadening ?H{sub 0} of 3??0.3 and 1??0.3?Oe, respectively. On the other hand, the post-oxidation method results in rough interface and higher retention of Boron in CoFeB leading to higher values for ? and ?H{sub 0} as 0.0080??0.0006 and 5??0.3?Oe, respectively.

Role of cross-shell excitations in the reaction 54Fe(d_pol,p)55Fe  

E-Print Network (OSTI)

The reaction 54Fe(d_pol,p)55Fe was studied at the Munich Q3D spectrograph with a 14 MeV polarized deuteron beam. Excitation energies, angular distributions and analyzing powers were measured for 39 states up to 4.5 MeV excitation energy. Spin and parity assignments were made and spectroscopic factors deduced by comparison to DWBA calculations. The results were compared to predictions by large scale shell model calculations in the full pf-shell and it was found that reasonable agreement for energies and spectroscopic factors below 2.5 MeV could only be obtained if up to 6 particles were allowed to be excited from the f_7/2 orbital into p_3/2, f_5/2, and p_1/2 orbitals across the N=28 gap. For levels above 2.5 MeV the experimental strength distribution was found to be significantly more fragmented than predicted by the shell model calculations.

Iron self-diffusion in amorphous FeZr?Fe57Zr multilayers measured by neutron reflectometry  

Science Journals Connector (OSTI)

Self-diffusion of iron in Fe67naturalZr33?Fe6757Zr33 multilayers has been investigated by neutron reflectometry. The as-deposited multilayer is amorphous in nature. It remains amorphous up to a temperature of 573K and thereafter nanocrystallizes with an average grain size of 6nm. The self-diffusion in the multilayers has been measured after isothermal vacuum annealing below the nanocrystallization temperature by monitoring the decay of the intensity of the first order Bragg peak, arising due to the isotopic periodicity. It has been found that the diffusivity at different temperatures follows an Arrhenius-type behavior with the preexponential factor D0=510?181m2s?1 and the activation energy E=0.380.05eV, respectively. These values of E and D0 follow the well-known ED0 correlation and on the basis of this correlation it is suggested that diffusion mechanism in the present case is not highly collective but involves a rather small group of atoms.

Assembly and Evolution of Complex Fe-S Clusters as Revealed by X-ray  

NLE Websites -- All DOE Office Websites (Extended Search)

Assembly and Evolution of Complex Fe-S Clusters Assembly and Evolution of Complex Fe-S Clusters as Revealed by X-ray Crystallography Complex Fe-S cluster-containing enzymes are ubiquitous in nature where they are involved in a number of fundamental reactions for life including carbon dioxide fixation, nitrogen fixation, and hydrogen metabolism. One of the more complex and unusual biological clusters is found in the [FeFe]-hydrogenase. The active-site H-cluster in these enzymes has a [4Fe-4S] subcluster bridged via a cysteine thiolate to a 2Fe subcluster, which in turn is coordinated by CO and CN- ligands and a bridging dithiolate ligand (1). The biologically unique CO and CN- ligands finely tune the 2Fe subcluster of the H-cluster making it able to efficiently catalyze the activation of molecular H2 through the reversible reaction H2 2H+ + 2e-. How this complex metallocluster is assembled in nature is intriguing and the precise mechanism by which various enzymes, scaffolds, and carriers carry out H-cluster maturation is unknown.

Fe thin-film growth on Au(100): A self-surfactant effect and its limitations  

Science Journals Connector (OSTI)

The combination of low-energy electron diffraction intensity analyses and scanning tunneling microscopy was used to investigate the morphology and atomic structure of thin Fe films grown on Au(100) at 400 K. Deposition of only about 0.2 monolayers (ML) Fe is sufficient to lift the reconstruction of the clean substrate. In the initial growth process (<~1 ML) place exchanges between Fe and Au lead to almost two-dimensional subsurface Fe film growth with one layer of Au covering the entire film. This way, gold acts as a self-surfactant. Yet, there are deviations from two-dimensional growth, with a second Fe layer beginning to grow before the first one is fully completed and some substitutional disorder developing in the film because of incomplete place exchange. The amount of gold floating on the surface only gradually decreases with further increasing film thickness. At about 2 ML the surface undergoes a complete restructuring during which short wormlike chains of atoms form and long-range order is destroyed. Nevertheless, the existence of large terraces of little roughness proves that some surface activity of gold remains. At coverages of several ML, long-range order is reestablished with the Fe film growing in an undistorted bcc arrangement. Although parts of the film are still covered by gold, the surface morphology is not very different from that known for homoepitaxial growth of Fe on Fe(100), i.e., gold has stopped to serve as a self-surfactant.

The structure and magnetic properties of lithiumiron pyrophosphate i.e. Li 2 Fe 3 ( P 2 O 7 ) 2 or LiFe 1.5 P 2 O 7 synthesized using a facile metal acetate approach for application in lithium-ion batteries are investigated in detail. The high-resolution transmission electron microscopy selected area electron diffraction and x-ray diffraction measurements indicate that Li 2 Fe 3 ( P 2 O 7 ) 2 is crystallized in the monoclinic structure without any indication of crystallographic defects such as dislocations or misfits and exhibit smooth surface morphology. The evaluated lattice parameters are a = 0.698 ? 76 ? nm b = 0.812 ? 36 ? nm c = 0.964 ? 22 ? nm and ? = 111.83 ( P 2 1 / c space group). Infrared spectroscopic measurements indicate the presence of P 2 O 7 groups which are formed by the two PO 4 tetrahedral groups connected together. The magnetic measurements indicate that Li 2 Fe 3 ( P 2 O 7 ) 2 is a weak antiferromagnetic material with T N = 20 ? K exhibiting a Curie constant C p = 3.38 ? emu ? K / mol per Fe ion and a negative value of the Weiss temperature ( ? p = ? 15 ? K ) . The absence of higher valence state Fe impurities and antiferromagnetic interactions due to the greater distance between two equivalent magnetic ions which vanishes the FeOFe superexchange interactions is confirmed.

Magnetization and Fe57 hyperfine fields in Y2Fe17Z3-?(Z=H, C, or N) interstitial compounds  

Science Journals Connector (OSTI)

Measured magnetization and Fe57 hyperfine fields at T?0 K for Y2Fe17 and Y2Fe17Z3-?, with Z=H, C, or N and ??0.5, are analyzed to determine the influence of the interstitial atoms on the 3d magnetism. All are weak ferromagnets with a nearly-full 3d subband, although when Z=N, the magnetic moment of 38.1?B is very close to the fully saturated value of 39.4?B. On a local scale, the order of hyperfine fields Bhf4f(=35 T)>Bhf6g (=33 T)>Bhf12j (=30 T)>Bhf12k (=28 T) is different from that of the local magnetic moments given by several recent band calculations for Y2Fe17, ?4f (=2.5?B)>?12j (=2.2?B)>?12k (=2.0?B)>?6g (=1.9 ?B), reflecting a large 4s-transferred hyperfine field at 6g sites which have very short Fe-Fe distances. The volume of samples with Z=C and N are identical, and so the chemical effects of the interstitials can be distinguished; both the local magnetic moment and hyperfine fields are systematically smaller in the carbide than the nitride by 5% and 12%, respectively.

The Extended Fe Distribution in the Intracluster Medium and the Implications Regarding AGN Heating  

Science Journals Connector (OSTI)

We present a systematic analysis of XMM-Newton observations of eight cool-core clusters of galaxies and determine the Fe distribution in the intracluster medium relative to the stellar distribution in the central dominant galaxy (CDG). Our analysis shows that the Fe is significantly more extended than the stellar mass in the CDG in all of the clusters in our sample, with a slight trend of increasing extent with increasing central cooling time. The excess Fe within the central 100 kpc in these clusters can be produced by Type Ia supernovae from the CDG over the past 3-7 Gyr. Since the excess Fe primarily originates from the CDG, it is a useful probe for determining the motion of the gas and the mechanical energy deposited by AGN outbursts over the past ~5 Gyr in the centers of clusters. We explore two possible mechanisms for producing the greater extent of the Fe relative to the stars in the CDG, bulk expansion of the gas and turbulent diffusion of the Fe. Assuming that the gas and Fe expand together, we find that a total energy of 1060-1061 erg s?1 must have been deposited into the central 100 kpc of these clusters in order to produce the currently observed Fe distributions. Since the required enrichment time for the excess Fe is approximately 5 Gyr in these clusters, this gives an average AGN mechanical power over this time of 1043-1044 erg s?1. The extended Fe distribution in cluster cores can also arise from turbulent diffusion. Assuming a steady state (i.e., the outward mass flux of Fe across a given surface is equal to the mass injection rate of Fe within that surface), we find that diffusion coefficients of 1029-1030 cm2 s?1 are required in order to maintain the currently observed Fe profiles. We find that heating by both turbulent diffusion of entropy and dissipation are important heating mechanisms in cluster cores. In half of the clusters with central cooling times greater than 1 Gyr, we find that heating by turbulent diffusion of entropy alone can balance radiative losses. In the remaining clusters, some additional heating by turbulent dissipation, with turbulent velocities of 150-300 km s?1, is required in order to balance radiative cooling. We also find that the average Type Ia supernova fraction within the central 100 kpc of these clusters is 0.53 (roughly twice the solar value), on the basis of the Si-to-Fe mass ratio. This implies a total (Type Ia plus core-collapse) supernova heating rate of less than 10% of the bolometric X-ray luminosity within the centers of clusters.

We used oxide molecular-beam epitaxy in a composition-spread geometry to deposit hexagonal LuFeO{sub 3} (h-LuFeO{sub 3}) thin films with a monotonic variation in the Lu/Fe cation ratio, creating a mosaic of samples that ranged from iron rich to lutetium rich. We characterized the effects of composition variation with x-ray diffraction, atomic force microscopy, scanning transmission electron microscopy, and superconducting quantum interference device magnetometry. After identifying growth conditions leading to stoichiometric film growth, an additional sample was grown with a rotating sample stage. From this stoichiometric sample, we determined stoichiometric h-LuFeO{sub 3} to have a T{sub N} = 147 K and M{sub s} = 0.018 ?{sub B}/Fe.

Spreading of Sn-Ag solders on FeNi alloys  

SciTech Connect

The spreading of Sn-3Ag-xBi solders on Fe-42Ni has been studied using a drop transfer setup. Initial spreading velocities as fast as {approx}0.5 m/s have been recorded. The results are consistent with a liquid front moving on a metastable, flat, unreacted substrate and can be described by using a modified molecular-kinetic model for which the rate controlling step is the movement of one atom from the liquid to the surface of the solid substrate. Although the phase diagram predicts the formation of two Fe-Sn intermetallics at the solder/substrate interface in samples heated at temperatures lower than 513 C, after spreading at 250 C only a thin FeSn reaction layer could be observed. Two interfacial layers (FeSn and FeSn2) were found after spreading at 450 C.

Enhancement of induced V polarization due to rough interfaces in polycrystalline V/Fe/V trilayers  

SciTech Connect

The effect of interface roughness on the induced polarization of V in polycrystalline V/Fe/V trilayers was investigated with x-ray magnetic circular dichroism, x-ray resonant magnetic scattering, and polarized neutron reflectometry. Trilayer samples were sputter deposited onto Si substrates at room temperature to minimize interdiffusion. The films were polycrystalline and exhibited an average 0.5 nm root-mean-square interfacial roughness at the Fe/V interfaces. The induced polarization found in V was constrained to the Fe/V interface extending approximately up to 2-3 monolayers into the V and exhibited antiferromagnetic alignment to the Fe layer. A magnetic moment for V ranging between -0.46 and -0.86 {micro}{sub B}/V atom is consistent with the neutron and resonant x-ray data. Notably, this value for structurally rough interfaces is significantly larger than that reported for samples with atomically flat Fe/V interfaces.

Engineering coercivity in epitaxially grown (110) films of DyFe 2 YFe 2 superlattices  

Science Journals Connector (OSTI)

Molecular beam epitaxial methods have been used to growsingle crystal Laves phase DyFe 2 YFe 2 superlattice samples with a (110) growth direction. It is shown that it is possible in principle to engineer a desired coercivity between the limits K DyFe 2 ?K??. This can be achieved by adjusting the relative thickness of the individual DyFe 2 and YFe 2 layers in multilayerfilms This novel feature is illustrated using the superlatticefilms [x?? DyFe 2 /(100-x)?? YFe 2 ]40 with x=80 60 50 and 45. It is found that the measured coercivity is in semiquantitative agreement with a simple theoretical expression for the nucleation fields in both bilayer and multilayer compounds. However in practice exchange spring penetration into the DyFe 2 layers can set a limit to the maximum coercivity that can be achieved.

Development of FeNiMoB thin film materials for microfabricated magnetoelastic sensors  

SciTech Connect

Metglas{sup TM} 2826MB foils of 25-30 {mu}m thickness with the composition of Fe{sub 40}Ni{sub 38}Mo{sub 4}B{sub 18} have been used for magnetoelastic sensors in various applications over many years. This work is directed at the investigation of {approx}3 {mu}m thick iron-nickel-molybdenum-boron (FeNiMoB) thin films that are intended for integrated microsystems. The films are deposited on Si substrate by co-sputtering of iron-nickel (FeNi), molybdenum (Mo), and boron (B) targets. The results show that dopants of Mo and B can significantly change the microstructure and magnetic properties of FeNi materials. When FeNi is doped with only Mo its crystal structure changes from polycrystalline to amorphous with the increase of dopant concentration; the transition point is found at about 10 at. % of Mo content. A significant change in anisotropic magnetic properties of FeNi is also observed as the Mo dopant level increases. The coercivity of FeNi films doped with Mo decreases to a value less than one third of the value without dopant. Doping the FeNi with B together with Mo considerably decreases the value of coercivity and the out-of-plane magnetic anisotropy properties, and it also greatly changes the microstructure of the material. In addition, doping B to FeNiMo remarkably reduces the remanence of the material. The film material that is fabricated using an optimized process is magnetically as soft as amorphous Metglas{sup TM} 2826MB with a coercivity of less than 40 Am{sup -1}. The findings of this study provide us a better understanding of the effects of the compositions and microstructure of FeNiMoB thin film materials on their magnetic properties.

Magnetoelectric coupling in polycrystalline FeVO4  

Science Journals Connector (OSTI)

We report coupling between magnetic and electric orders for antiferromagnetic polycrystalline FeVO4 in which magnetism-induced polarization has been recently found in noncollinear antiferromagnetic state below the second antiferromagnetic phase transition at TN2?15.7?K. In this low symmetry phase space group P1, the magnetic field dependence of electric polarization evidences a clear magnetoelectric coupling in the noncollinear spin-configured antiferromagnetic phase. The discontinuity of magnetodielectric effect observed at the vicinity of the polar to nonpolar transition evidences competition between different magnetodielectric couplings in the two different antiferromagnetic states. The existence of thermal expansion anomaly near TN2 and magnetostriction effect support magnetoelastically mediated scenario of the observed magnetoelectric effect.

Lattice relaxations and hyperfine fields of heavy impurities in Fe  

Science Journals Connector (OSTI)

We present first-principles calculations of the lattice relaxations and hyperfine fields of heavy impurities in bcc Fe. We consider impurities of the 5sp and 6sp series, containing the largest atoms in the periodic table. As an application we calculate the hyperfine fields of these impurities and in particular the effects of lattice relaxations on these fields. The calculations are based on a full-potential Korringa-Kohn-Rostoker Greens-function method for defects and employ the local spin-density approximation for the exchange and correlation effects. The nonspherical parts of the potential and the charge density are included in the calculations and the forces are calculated by an ionic version of the Hellmann-Feynman theorem. The resulting lattice relaxations are relatively small, even for the largest impurities considered. The comparison of the calculated hyperfine fields with the experimental data shows that the inclusion of lattice relaxations improves the overall agreement with experiment.

Hardness of FeB{sub 4}: Density functional theory investigation  

SciTech Connect

A recent experimental study reported the successful synthesis of an orthorhombic FeB{sub 4} with a high hardness of 62(5) GPa [H. Gou et al., Phys. Rev. Lett. 111, 157002 (2013)], which has reignited extensive interests on whether transition-metal borides compounds will become superhard materials. However, it is contradicted with some theoretical studies suggesting transition-metal boron compounds are unlikely to become superhard materials. Here, we examined structural and electronic properties of FeB{sub 4} using density functional theory. The electronic calculations show the good metallicity and covalent FeB bonding. Meanwhile, we extensively investigated stress-strain relations of FeB{sub 4} under various tensile and shear loading directions. The calculated weakest tensile and shear stresses are 40 GPa and 25 GPa, respectively. Further simulations (e.g., electron localization function and bond length along the weakest loading direction) on FeB{sub 4} show the weak FeB bonding is responsible for this low hardness. Moreover, these results are consistent with the value of Vickers hardness (11.732.3 GPa) by employing different empirical hardness models and below the superhardness threshold of 40 GPa. Our current results suggest FeB{sub 4} is a hard material and unlikely to become superhard (>40 GPa)

Near-IR [Fe II] emission diagnostics applied to cold disk winds in young stars  

E-Print Network (OSTI)

We investigate the emissivity properties of the main near-IR transitions of the Fe+ ion in the conditions prevailing in the inner regions of jets from young stars, based on a simplified 16-level atom model. We present new diagnostic diagrams involving prominent near-IR line ratios that allow us to constrain the electronic density, temperature, and Fe gas phase abundance ratio, independently of the heating process. Comparison with recent near-IR observations of a sample of HH objects indicates gas phase Fe abundances ranging from 15-50 % up to 100 % of the solar value in agreement with the moderate depletions previously derived from optical line ratios or shock models. Hence, it appears that Fe-bearing dust is efficiently destroyed in stellar jets. We then use our Fe+ emissivity model to predict near-IR [Fe II] emission maps for self-similar, cold MHD disk wind models. We show that observations in [Fe II] with AMBER on the VLTI could severely constrain the MHD solution and the inner launch radius of the jet. W...

Distribution of Si, Fe, and Ni in the Intracluster Medium of the Coma Cluster  

E-Print Network (OSTI)

We studied the distributions of Si, Fe, and Ni in the intracluster medium (ICM) of the Coma cluster, one of the largest clusters in the nearby universe, using XMM-Newton data up to 0.5 r180 and Suzaku data of the central region up to 0.16 r180. Using the flux ratios of Ly alpha of H-like Si and 7.8 keV blend to K alpha of He-like Fe, the abundance ratios of Si to Fe and Ni to Fe of the ICM were derived using APEC model v2.0.1. The Si/Fe ratio in the ICM of the Coma cluster shows no radial gradient. The emission weighted averages of the Si/Fe ratio in the ICM within 0.0--0.2 r180, 0.2--0.5 r180, and 0.0--0.5 r180 are 0.97 +- 0.11, 1.05 +- 0.36 and 0.99 +- 0.13, respectively, in solar units using the solar abundance of Lodders (2003). These values are close to those of smaller clusters and groups of galaxies. Using the Suzaku data of the central region, the derived Ni/Fe ratio of the ICM is 0.6--1.5 in solar units, according to the same solar abundance table.

AlFe PILC preparation, characterization and its potential adsorption capacity for aflatoxin B1  

Science Journals Connector (OSTI)

Abstract Montmorillonite (Mt) was used as the precursor material for synthesis of aluminumironpillared montmorillonite (AlFePMt) and the adsorption of aflatoxin B1 (AFB1) by Mt and AlFePMt was investigated. Different forms of polycations were prepared and used to modify Mt, when the molar ratio of Al3+ to Fe3+ was 8.0, AlFePMt obtained the maximum adsorption capacity of AFB1 (660.0?g/g) which was much higher than that of Mt (30.4?g/g). The adsorbents were characterized by XRD, SEM and FTIR, and the effects of adsorbent amount, pH and interaction time on the adsorption of AFB1 onto Mt and AlFePMt were also studied. Adsorption isotherm parameters were obtained from Langmuir and Freundlich and the adsorption data fitted better to Langmuir. The obtained results show that the great difference of adsorption capacity between Mt and AlFePMt mainly lies in their microstructure and chemical composition, and it suggests that AlFePMt is suitable to be used as a potential adsorbent to remove AFB1 from the contaminated products.

Phonon and magnetic dimer excitations in Fe-based S=2 spin-ladder compound BaFe2Se2O  

Science Journals Connector (OSTI)

Raman scattering spectra of the new Fe-based S=2 spin-ladder compound BaFe2Se2O are measured in a temperature range between 15 and 623 K. All six A1g and two B1g Raman active modes of BaFe2Se2O, predicted by the factor-group analysis, have been experimentally observed at energies that are in a rather good agreement with the lattice dynamics calculation. The antiferromagnetic long-range spin ordering in BaFe2Se2O below TN=240 K leaves a fingerprint both in the A1g and B1g phonon mode linewidth and energy. In the energy range between 400 and 650 cm?1 we have observed a magnetic excitation related structure in the form of a magnon continuum, with the peaks corresponding to the singularities in the one-dimensional density of magnon states. The onset value of magnetic continuum (2?S) is found at about 437 cm?1 at 15 K. The magnetic continuum disappears at about 623 K, which led us to conclude that the short-range magnetic ordering in BaFe2Se2O exists apparently up to 2.6TN.

Fabrication of Fe16N2 Films by Sputtering Process and Experimental Investigation of Origin of Giant Saturation Magnetization in Fe16N2  

SciTech Connect

We present a systematic study to address a longstanding mystery in magnetic materials and magnetism, whether there is giant saturation magnetization in Fe{sub 16}N{sub 2} and why. Experimental results based on sputtered thin film samples are presented. The magnetism of Fe{sub 16}N{sub 2} is discussed systematically from the aspects of material processing, magnetic characterization and theoretical investigation. It is observed that thin films with Fe{sub 16}N{sub 2}+Fe{sub 8}N mixture phases and high degree of N ordering, exhibit a saturation magnetization up to 2.68T at room temperature, which substantially exceeds the ferromagnetism limit based on the traditional band magnetism understanding. From X-ray magnetic circular Dichorism (XMCD) experiment, transport measurement and first-principle calculation based on LDA+U method, it is both experimentally and theoretically justified that the origin of giant saturation magnetization is correlated with the formation of highly localized 3d electron states in this Fe-N system. A large magnetocrystalline anisotropy for such a material is also discussed. Our proposed 'cluster+atom' theory provides promising directions on designing novel magnetic materials with unique performances.

Granular L1{sub 0} FePt-B and FePt-B-Ag (001) thin films for heat assisted magnetic recording  

SciTech Connect

A comparison was made of FePt-B and FePt-B-Ag thin films having different volume contents of boron, which were RF sputtered with in-situ heating at 425-575 deg. C onto Si substrates with 20 nm thick (002) MgO. By introducing boron into FePt and varying the sputtering conditions, films with grain sizes ranging from 2.5 to 10 nm were produced. The boron promoted columnar growth, but made ordering more difficult. However, by adding Ag into FePt-B, ordering improved while coercivity increased from 7 to 11 kOe with no significant impact on the microstructure. We obtained films with grain sizes down to 2.5 nm with center-to-center spacing of 3.1 nm. The reduced grain size, columnar microstructure and increase in ordering and coercivity by adding Ag into the FePt-B thin films are favorable for application in heat assisted magnetic recording.

Enhancement of exchange bias and training effect in ion-beam sputtered Fe{sub 46}Mn{sub 54}/Ni{sub 81}Fe{sub 19} bilayers  

SciTech Connect

We present a remarkable enhancement by 300% of the exchange-bias field at room temperature, without affecting the coercivity value, via optimum magnetic annealing (250?C/3 kOe) in ion-beam sputtered FeMn(30?nm)/NiFe(10?nm) bilayers. This specific behavior has been attributed to a higher degree of ?-FeMn(111) orientation that offers more interfacial FeMn moments to get pinned with the moments of the adjacent NiFe layer. Unlike the absence of training effect at room temperature, a pronounced training effect and an accompanying magnetization reversal asymmetry are evidenced upon field cooling below 50?K due to the presence of biaxial exchange induced anisotropy across the interdiffused FeMn/NiFe interface. The present findings not only have technological significance but also are of relevance to the understanding of interfacial spin disorder and frustration in these exchange-biased systems.

A theoretical study of the electronic structure of Invar Fe*3Pt and related materials  

SciTech Connect

The Full Potential Linear Augmented Plane Wave (FPLAPW or FLAPW) method is used for a spin-polarized band calculation for ordered Fe{sub 3}Pt. As major purpose, the momentum distributions of the spin-polarized electrons are calculated and compared with results from a magnetic Compton scattering measurement. To get related information, the electronic behavior is also analyzed by examining the partial densities of states and the spatial electron distributions; the role of alloying effects is then explored by studying the electrons in some related alloys: Fe{sub 3}Ni, Fe{sub 3}Pd, Ni{sub 3}Pt and Co{sub 3}Pt.

A Minimal Two-band Model for the Superconducting Fe-pnictides  

SciTech Connect

Following the discovery of the Fe-pnictide superconductors, LDA band structure calculations showed that the dominant contributions to the spectral weight near the Fermi energy came from the Fe 3d orbitals. The Fermi surface is characterized by two hole surfaces around the {Lambda} point and two electron surfaces around the M point of the 2 Fe/cell Brillouin zone. Here, we describe a 2-band model that reproduces the topology of the LDA Fermi surface and exhibits both ferromagnetic and q = ({pi}, 0) spin density wave (SDW) fluctuations. We argue that this minimal model contains the essential low energy physics of these materials.

Magnetic field induced discontinuous spin reorientation in ErFeO{sub 3} single crystal  

SciTech Connect

The spin reorientation of ErFeO{sub 3} that spontaneously occurs at low temperature has been previously determined to be a process involving the continuous rotation of Fe{sup 3+} spins. In this work, the dynamic process of spin reorientation in ErFeO{sub 3} single crystal has been investigated by AC susceptibility measurements at various frequencies and static magnetic fields. Interestingly, two completely discontinuous steps are induced by a relatively large static magnetic field due to the variation in the magnetic anisotropy during this process. It provides deeper insights into the intriguing magnetic exchange interactions which dominate the sophisticated magnetic phase transitions in the orthoferrite systems.

In this study, we used the first-principles density functional theory calculation method to determine how Pt surface segregation (exchanging interior Pt with surface Fe atoms) would affect the magnetic properties of L1{sub 0} ordered FePt nanoparticles. For both cuboid and cuboctahedral FePt nanoparticles, we predicted that the Pt surface segregation process could cause a decrease in total magnetic moments, a change in (easy and/or hard) magnetization axes, and a reduction in magnetic anisotropy.

Magnetism and transport properties of epitaxial Fe-Ga thin films on GaAs(001)  

SciTech Connect

Epitaxial Fe-Ga thin films in disordered bcc {alpha}-Fe crystal structure (A2) have been grown on GaAs(001) by molecular beam epitaxy. The saturated magnetization (M{sub S}) decreased from 1371 to 1105 kA/m with increasing Ga concentration from 10.5 to 24.3 % at room temperature. The lattice parameter increased with the increase in Ga content because of the larger atomic radius of Ga atom than that of Fe. The increase in carrier density with Ga content caused in lower resistivity.

Relationships between Fe redistribution and Po2 during mineral dissolution under low O2 conditions  

Science Journals Connector (OSTI)

Iron-bearing olivine was dissolved at different partial pressures of atmospheric oxygen (Po2) in a glove box to clarify the relationships between Fe redistribution and Po2 during mineral dissolution and to provide a deeper understanding of weathering under low oxygen conditions. The olivine was first dissolved at pH 4.56.0 and 1555C under the ambient air using a modified flow-through system. Some portion of Fe2+ released from olivine was oxidized and precipitated as Fe3+ oxides/hydroxides, and remained in the system, while the other portion flowed out of the system as Fe2+. Then, a kinetic model, considering mineral dissolution, water flow and Fe2+ oxidation rates, was made to estimate Fe behavior at different pHs, temperatures and dissolved O2 concentrations during dissolution. The kinetic model was applied to the experimental results under the ambient air; the validity of the model was confirmed by good agreement between the observed and calculated ? values where ? is a ratio of the amount of Fe3+ precipitated to the total amount of Fe2+ actually dissolved from olivine, an indicator of the oxidation state of a mineral dissolution system. Then, by using the kinetic model, we analyzed the results of the olivine dissolution experiments at 0.20 atm to 8.7נ105atm of Po2 and at constant pH and temperature. While the dissolution rates of olivine were not affected significantly by Po2, the olivine dissolution has indicated that ? decreases with decrease in Po2 and the ? variation at low Po2 cannot be explained by the classic rate law of Fe2+ oxidation. The calculations of ? based on the above kinetic model have revealed that the observed ? variation is well explained by the decrease in the power of [O2] (x) with decrease in [O2] for the Fe2+ oxidation rate, d[Fe2+]/dt=k[Fe2+][O2]x[OH]y (k: the rate constant, 0?x?1, and y?2); the x value decreased from 1.0 to 0.76 at 0.20 to 8.7נ105atm of Po2, respectively. The ??Po2 relationships imply that the ? value in a paleosol (fossil weathering profile) increases with increase in Po2 in the Paleoproterozoic.

The adsorption of H2 on Fe-coated C5H5 and its application in hydrogen storage  

Science Journals Connector (OSTI)

Abstract Based on density functional theory, the capacities of FeC5H5, Fe2C5H5 and one-dimensional (FeC5H5)? nanowire as hydrogen storage media were investigated. The results show that FeC5H5 and Fe2C5H5 can adsorb five and ten H2 molecules, respectively, and form stable FeC5H5(H2)5 and Fe2C5H5(H2)10 systems. The hydrogen storage capacities of the two systems are 7.63wt% and 10.15wt%, while the average adsorption energies are 0.49 and 0.73eV/H2, indicating that FeC5H5 and Fe2C5H5 are excellent hydrogen storage media. In addition, (FeC5H5)? nanowire can also adsorb H2 molecules (1.62wt%). Most importantly, the magnetic and electrical properties of the nanowire are sensitive to the additional H2, thus (FeC5H5)? can be used for selecting and detecting H2 molecules.

Magnetism of an Fe monolayer on W(110)  

Science Journals Connector (OSTI)

We discuss theoretical studies of magnetism in the Fe monolayer adsorbed on the W(110) surface. We first present density-functional studies of the ground state that provide us with basic magnetic parameters, under the assumption the ground state is ferromagnetic. We provide results for the spin and orbital magnetic moments, local density of states, the anisotropy, and measures of the exchange strength as provided by calculations of the energy difference between the ferromagnetic and antiferromagnetic states. We compare these results with those provided by the empirical tight-binding description we have used to describe spin waves in this system, to find good agreement between the two methods where results overlap. Inclusion of spin-orbit coupling within our tight-binding Hamiltonian produces anisotropy close in strength and character to that which emerges from the full density-functional analysis, for example. We then present new calculations of the nature of the spin waves in the monolayer. We point out that the large anisotropy that emerges from our analyses (similar to that found in earlier work), combined with our calculations of the effective exchange, provides a value for the Curie temperature of the film much larger than that found experimentally. An earlier experimental study has suggested that in this system, the effective exchange is much smaller than we find. We conclude that the magnetism in this much studied system is not well understood. We discuss reasons why this may be so.

Improvement of magnetic properties of FePt nanoparticles by adding Mn  

SciTech Connect

FePtMn nanoparticles were synthesized by the simultaneous reduction of iron acetylacetonate, platinum acetylacetonate, and manganese acetylacetonate with 1,2-hexadecanediol as the reducing reagent in the polyol process. The coercivity of annealed nanoparticles strongly depends on the amount of Mn addition. A maximum coercivity of 19 kOe at room temperature was obtained for (Fe{sub 32}Pt{sub 68}){sub 87}Mn{sub 13} nanoparticles annealed at 700 deg. C for 1 h. The presence of Mn in the FePt L1{sub 0} lattice may induce local strain so the ordering is accelerated. In addition, the high coercivity can presumably be partially related to the local bonding of Pt-Mn (or Fe-Mn) in the L1{sub 0} structure.

Pressure tuning of competing magnetic interactions in intermetallic CeFe2  

SciTech Connect

We use high-pressure magnetic x-ray diffraction and numerical simulation to determine the low-temperature magnetic phase diagram of stoichiometric CeFe2. Near 1.5 GPa we find a transition from ferromagnetism to antiferromagnetism, accompanied by a rhombohedral distortion of the cubic Laves crystal lattice. By comparing pressure and chemical substitution we find that the phase transition is controlled by a shift of magnetic frustration from the Ce-Ce to the Fe-Fe sublattice. Notably the dominant Ce-Fe magnetic interaction, which sets the temperature scale for the onset of long-range order, remains satisfied throughout the phase diagram but does not determine the magnetic ground state. Our results illustrate the complexity of a system with multiple competing magnetic energy scales and lead to a general model for magnetism in cubic Laves phase intermetallic compounds.

Charge transfer in Fe-doped GaN: The role of the donor  

SciTech Connect

Several nitride-based device structures would benefit from the availability of high quality, large-area, freestanding semi-insulating GaN substrates. Due to the intrinsic n-type nature of GaN, however, the incorporation of compensating centers such as Fe is necessary to achieve the high resistivity required. We are using electron paramagnetic resonance (EPR) to explore charge transfer in 450 um thick GaN:Fe plates to understand the basic mechanisms related to compensation so that the material may be optimized for device applications. The results suggest that the simple model based on one shallow donor and a single Fe level is insufficient to describe compensation. Rather, the observation of the neutral donor and Fe3+ indicates that either the two species are spatially segregated or additional compensating and donor defects must be present.

Absence of long-range chemical ordering in equimolar FeCoCrNi  

SciTech Connect

Equimolar FeCoCrNi alloys have been the topic of recent research as 'high-entropy alloys,' where the name is derived from the high configurational entropy of mixing for a random solid solution. Despite their name, no systematic study of ordering in this alloy system has been performed to date. Here, we present results from anomalous x-ray scattering and neutron scattering on quenched and annealed samples. An alloy of FeNi{sub 3} was prepared in the same manner to act as a control. Evidence of long-range chemical ordering is clearly observed in the annealed FeNi{sub 3} sample from both experimental techniques. The FeCoCrNi sample given the same heat treatment lacks long-range chemical order.

Magnetic structure in Fe/Sm-Co exchange spring bilayers with intermixed interfaces.  

SciTech Connect

The depth profile of the intrinsic magnetic properties in an Fe/Sm-Co bilayer fabricated under nearly optimal spring-magnet conditions was determined by complementary studies of polarized neutron reflectometry and micromagnetic simulations. We found that at the Fe/Sm-Co interface, the magnetic properties change gradually at the length scale of 8 nm. In this intermixed interfacial region, the saturation magnetization and magnetic anisotropy are lower and the exchange stiffness is higher than values estimated from the model based on a mixture of Fe and Sm-Co phases. Therefore, the intermixed interface yields superior exchange coupling between the Fe and Sm-Co layers, but at the cost of average magnetization.

Room temperature ferromagnetism in undoped and Fe doped ZnO nanorods: Microwave-assisted synthesis  

SciTech Connect

One-dimensional (1D) undoped and Fe doped ZnO nanorods of average length {approx}1 {mu}m and diameter {approx}50 nm have been obtained using a microwave-assisted synthesis. The magnetization (M) and coercivity (H{sub c}) value obtained for undoped ZnO nanorods at room temperature is {approx}5x10{sup -3} emu/g and {approx}150 Oe, respectively. The Fe doped ZnO samples show significant changes in M -H loop with increasing doping concentration. Both undoped and Fe doped ZnO nanorods exhibit a Curie transition temperature (T{sub c}) above 390 K. Electron spin resonance and Moessbauer spectra indicate the presence of ferric ions. The origin of ferromagnetism in undoped ZnO nanorods is attributed to localized electron spin moments resulting from surface defects/vacancies, where as in Fe doped samples is explained by F center exchange mechanism. -- Graphical abstract: Room temperature ferromagnetism has been reported in undoped and Fe doped ZnO nanorods of average length {approx}1 {mu}m and diameter {approx}50 nm.

Near-IR [Fe II] emission diagnostics applied to cold disk winds in young stars  

E-Print Network (OSTI)

We investigate the emissivity properties of the main near-IR transitions of the Fe+ ion in the conditions prevailing in the inner regions of jets from young stars, based on a simplified 16-level atom model. We present new diagnostic diagrams involving prominent near-IR line ratios that allow us to constrain the electronic density, temperature, and Fe gas phase abundance ratio, independently of the heating process. Comparison with recent near-IR observations of a sample of HH objects indicates gas phase Fe abundances ranging from 15-50 % up to 100 % of the solar value in agreement with the moderate depletions previously derived from optical line ratios or shock models. Hence, it appears that Fe-bearing dust is efficiently destroyed in stellar jets. We then use our Fe+ emissivity model to predict near-IR [Fe II] emission maps for self-similar, cold MHD disk wind models. We show that observations in [Fe II] with AMBER on the VLTI could severely constrain the MHD solution and the inner launch radius of the jet. We also compare theoretical predictions with recent observations in the near-IR [Fe II] lines of the L1551-IRS5 and DG Tau jets. The cold disk wind model reproduces quite well the two velocity components observed at -100 and -300 km/s, although the high velocity component appears overestimated by a factor of 1.5 in the DG Tau jet. However, the model predicts too little emission at intermediate-velocity and insufficient densities. Denser disk winds with stronger heating at the jet base, which have been invoked for optical jets, also appear needed in younger, embedded Class I jet sources.

Science Journals Connector (OSTI)

Delaminated Fe-exchanged Ti-pillared interlayered montmorillonite (FeTi-PILC) was prepared and its catalytic performance as heterogeneous catalyst in wet hydrogen peroxide oxidation of phenol employing microwave irradiation was firstly evaluated. The obtained results indicated that the application of the catalyst allows a comparatively high removal of COD and a total elimination of phenol under mild conditions, without obvious leaching of iron species. The introduction of microwave irradiation could greatly shorten the reaction time.

Different response of the crystal structure to isoelectronic doping in BaFe2(As1?xPx)2 and (Ba1?xSrx)Fe2As2  

Science Journals Connector (OSTI)

Superconductivity up to 30 K in charge neutrally doped BaFe2(As1?xPx)2 has been ascribed to chemical pressure caused by the shrinking unit cell. But the latter induces no superconductivity in (Ba1?xSrx)Fe2As2 in spite of the same volume range. We show that the spin-density-wave (SDW) state of BaFe2As2 becomes suppressed in BaFe2(As1?xPx)2 by a subtle reorganization of the crystal structure, where arsenic and phosphorus are located at different coordinates zAs and zP. High-resolution x-ray diffraction experiments with BaFe2(As1?xPx)2 single crystals reveal almost unchanged Fe-P bonds, but a contraction of the Fe-As bonds, which remain nearly unchanged in (Ba1?xSrx)Fe2As2. Since the Fe-As bond length is a gauge for the magnetic moment, our results show why the SDW is suppressed by P doping, but not by Sr doping. Only the Fe-P interaction increases the width of the iron 3d bands, which destabilizes the magnetic SDW ground state. The simultaneous contraction of the Fe-As bonds is rather a consequence of the vanishing magnetism. Ordered structure models of BaFe2(As1?xPx)2 obtained by density-functional theory calculations agree perfectly with the single-crystal x-ray structure determinations. The contraction of the Fe-As bonds saturates at doping levels above x?0.3, which corrects the unreasonable linear decrease in the so-called pnictide height.

Preservation of Fe(II) by Carbon-Rich Matrices in Hydrothermal Plumes Print Preservation of Fe(II) by Carbon-Rich Matrices in Hydrothermal Plumes Print Despite the considerable amount of iron that enters the oceans from the continents and from hydrothermal vents at mid-ocean ridges on the seafloor, there are large regions of the global ocean where iron availability is so low that it limits life. Oceanographers have long explained this anomaly by assuming that the iron in the sea is primarily incorporated as Fe(III) into inorganic minerals that lack both the mobility to circulate over long distance and bioavailability to sea life as an essential nutrient. Now, a collaboration led by researchers from the Woods Hole Oceanographic Institution has reported that the hydrothermal plumes emerging from the vents actually contain iron in both Fe(II) and Fe(III) oxidation states associated with organic material from nearby flora and fauna. The collaboration suggests that the organic matrices prevent oxidation and precipitation of the Fe(II), perhaps increasing both its circulation through the world's oceans and its bioavailability as a deep-sea nutrient.

Magnetic excitations and anomalous spin-wave broadening in multiferroic FeV2O4  

SciTech Connect

We report on the different roles of two orbital-active Fe2+ at the A site and V3+ at the B site in the magnetic excitations and on the anomalous spin-wave broadening in FeV2O4. FeV2O4 exhibits three structural transitions and successive paramagnetic (PM)collinear ferrimagnetic (CFI)noncollinear ferrimagnetic (NCFI)/ferroelectric transitions. The high-temperature tetragonal/PMorthorhombic/CFI transition is accompanied by the appearance of a large energy gap in the magnetic excitations due to strong spin-orbit-coupling-induced anisotropy at the Fe2+ site. While there is no measurable increase in the energy gap from the orbital ordering of V3+ at the orthorhombic/CFItetragonal/NCFI transition, anomalous spin-wave broadening is observed in the orthorhombic/CFI state due to V3+ spin fluctuations at the B site. The spin-wave broadening is also observed at the zone boundary without softening in the NCFI/ferroelectric phase, which is discussed in terms of magnon-phonon coupling. Our study also indicates that the Fe2+ spins without the frustration at the A site may not play an important role in inducing ferroelectricity in the tetragonal/NCFI phase of FeV2O4.

Optimization of LiFePO4 Nanoparticle Suspensions with Polyethyleneimine for Aqueous Processing  

SciTech Connect

Addition of dispersants to aqueous based lithium-ion battery electrode formulations containing LiFePO{sub 4} is critical to obtaining a stable suspension. The resulting colloidal suspensions enable dramatically improved coating deposition when processing electrodes. This research examines the colloidal chemistry modifications based on polyethyleneimine (PEI) addition and dispersion characterization required to produce high quality electrode formulations and coatings for LiFePO{sub 4} active cathode material. The isoelectric point, a key parameter in characterizing colloidal dispersion stability, of LiFePO{sub 4} and super P C45 were determined to be pH = 4.3 and 3.4, respectively. PEI, a cationic surfactant, was found to be an effective dispersant. It is demonstrated that 1.0 wt % and 0.5 wt % PEI were required to stabilize the LiFePO{sub 4} and super P C45 suspension, respectively. LiFePO{sub 4} cathode suspensions with 1.5 wt % PEI demonstrated the best dispersibility of all components, as evidenced by viscosity and agglomerate size of the suspensions and elemental distribution within dry cathodes. The addition of PEI significantly improved the LiFePO{sub 4} performance.

Pressure driven spin crossover and isostructural phase transition in LaFeO{sub 3}  

SciTech Connect

We have studied the behavior of LaFeO{sub 3} under pressure (P) using density functional theory (DFT) and atomistic simulations. Ground state structural properties of LaFeO{sub 3} are correctly described by atomistic simulations. The effect of high pressure shows that there is an isotropic compression up to 100?GPa. However, DFT calculations show that within pressure range 0?FeO{sub 3} retains its ground state electronic structure. On the other hand, at P ?32.4?GPa high to low spin magnetic phase transition is observed, which is accompanied by 6.9% volume collapse of LaFeO{sub 3} unit cell, while retaining the ground state orthorhombic crystal structure, i.e., isostructural phase transition. Furthermore, the band gap is closed leading insulator to metal transition. This differing behavior observed by the two techniques can be attributed to the omission of magnetic effects in static simulations. The simultaneous magnetic, electrical, and structural (volume collapse) phase transitions of LaFeO{sub 3} under compression as revealed by DFT calculations corroborate experimental findings. From these results, we can elaborate the mechanism of phase transition in LaFeO{sub 3}: increasing crystal field induces a high spin to low spin transition, which in turn drives the electrical transitions and volume collapse.

GaFeO{sub 3}-type AlFeO{sub 3} is consisted of oxygen octahedra and tetrahedra containing Al and Fe ions and is known to have a non-centrosymmetric polar structure with space group Pna2{sub 1}. We tried to grow epitaxial GaFeO{sub 3}-type AlFeO{sub 3} films on SrTiO{sub 3} (111) substrates by pulsed laser deposition technique. Both the atomic arrangement of close-packed and the atomic distance of the substrate surface played important roles in stabilizing GaFeO{sub 3}-type AlFeO{sub 3} on the substrate. Piezoresponse force microscopy measurements clearly showed that GaFeO{sub 3}-type AlFeO{sub 3} films have ferroelectricity at room temperature. In addition, AlFeO{sub 3} film also showed pinched-like hysteresis loop with T{sub N}???317?K.

Dopant spin states and magnetism of Sn{sub 1?x}Fe{sub x}O{sub 2} nanoparticles  

SciTech Connect

This work reports detailed investigations of a series of ?2.6?nm sized, Sn{sub 1?x}Fe{sub x}O{sub 2} crystallites with x?=?00.10 using Mossbauer spectroscopy, x-ray photoelectron spectroscopy (XPS), electron paramagnetic resonance spectroscopy (EPR), and magnetometry to determine the oxidation state of Fe dopants and their role in the observed magnetic properties. The magnetic moment per Fe ion ? was the largest ?6.48??10{sup ?3} ?{sub B} for the sample with the lowest (0.001%) Fe doping, and it showed a rapid downward trend with increasing Fe doping. Majority of the Fe ions are in 3+ oxidation state occupying octahedral sites. Another significant fraction of Fe dopant ions is in 4+ oxidation state and a still smaller fraction might be existing as Fe{sup 2+} ions, both occupying distorted sites, presumably in the surface regions of the nanocrystals, near oxygen vacancies. These studies also suggest that the observed magnetism is not due to exchange coupling between Fe{sup 3+} spins. A more probable role for the multi-valent Fe ions may be to act as charge reservoirs, leading to charge transfer ferromagnetism.

Combustion wave speeds of nanocomposite Al/Fe2O3: the effects of Fe2O3 particle synthesis technique  

Science Journals Connector (OSTI)

Combustion wave speeds of nanoscale aluminum (Al) powders mixed with iron oxide (Fe2O3) were measured as a function of Fe2O3 synthesis technique and fuel/oxidizer composition. Three reactant synthesis techniques were examined; two focus on solgel processing of nanoscale Fe2O3 particles and the third utilizes commercially available nanoscale Fe2O3 powder. Nanoscale aluminum particles (52 nm in diameter) were combined with each oxidizer in various proportions. Flame propagation was studied by igniting low-density mixtures and taking data photographically with a high-speed camera. Both open and confined burning were examined. Results indicate that the combustion wave speed is a strong function of the stoichiometry of the mixture and a slightly fuel-rich mixture provides an optimum combustion wave speed regardless of oxidizer synthesis technique. Oxidizers processed using solgel chemistry originally contained impurities which retarded the combustion wave speeds. When the same oxidizers are annealed at moderate temperatures, the new heat-treated oxidizer shows a dramatic improvement, with combustion wave speeds on the order of 900 m/s.

Inelastic tunneling conductance and magnetoresistance investigations in dual ion-beam sputtered CoFeB(110)/MgO/CoFeB (110) magnetic tunnel junctions  

SciTech Connect

Magnetic tunnel junctions (MTJs) comprising Ta(5)/NiFe(5)/IrMn(15)/CoFeB(5)/Mg(1)/MgO(3.5)/ CoFeB(5)/Ta(5)/Ag(20) (thickness in nm) with (110) oriented CoFeB layers are grown using dual ion beam sputtering. The tunnel magnetoresistance (TMR) of MTJs is found to be significantly bias dependent and exhibits zero bias anomaly (ZBA) which is attributed to the presence of magnetic impurities or diffusion of Mn from antiferromagnetic IrMn in the barrier. Adjacent to the ZBA, two peaks at 24??3?mV and 34??3?mV are also observed, which differ both in intensity as well as their position in the antiparallel and parallel magnetic states, suggesting that they are due to magnon excitations. In addition to this, a phonon peak at 65??3?mV is also observed. The effect of temperature on the inelastic and elastic tunneling contributions is studied in detail in 25300?K range using the Glazman and Matveev model. Ten series of localized states are found to be involved in hopping conduction in the forbidden gap of MgO barrier. The effect of presence of such inelastic channels is found to be insignificant at low temperatures yielding sizeable enhancement in TMR.

Surface Patterns of Tetragonal Phase FePt Thin Films from Pt{at}Fe2O3 Core-Shell Nanoparticles Using Combined Langmuir-Blodgett and Soft Lithographic Techniques  

SciTech Connect

OAK B204 We present the fabrication of micron-sized patterns of FePt thin films from Pt{at}Fe2O3 core-shell nanoparticles. In a typical procedure, Pt@Fe2O3 core-shell nanoparticles were spread and formed a Langmuir film using water as the subphase. This film was lifted onto polydimethylsiloxane (PDMS) stamps with micron-sized patterns of lines, dots and wells, and transferred onto silicon wafers using microcontact printing (u-CP). The patterns of Pt@Fe2O3 core-shell nanoparticles were converted into face-centered tetragonal phase FePt alloy at enhanced temperatures in the presence of 5% hydrogen. Scanning electron microscopy (SEM), atomic force microscopy (AFM), powder X-ray diffraction (PXRD) and superconducting quantum interference device (SQUID) magnetometer were used to characterize the patterns and the properties of the final FePt alloy films.

Fe K?emission from photoionized slabs: the impact of the iron abundance  

E-Print Network (OSTI)

Iron K\\alpha emission from photoionized and optically thick material is observed in a variety of astrophysical environments including X-ray binaries, active galactic nuclei, and possibly gamma-ray bursts. This paper presents calculations showing how the equivalent width (EW) of the Fe K line depends on the iron abundance of the illuminated gas and its ionization state -- two variables subject to significant cosmic scatter. Reflection spectra from a constant density slab which is illuminated with a power-law spectrum with photon-index \\Gamma are computed using the code of Ross & Fabian. When the Fe K EW is measured from the reflection spectra alone, we find that it can reach values greater than 6 keV if the Fe abundance is about 10 times solar and the illuminated gas is neutral. EWs of about 1 keV are obtained when the gas is ionized. In contrast, when the EW is measured from the incident+reflected spectrum, the largest EWs are ~800 keV and are found when the gas is ionized. When \\Gamma is increased, the Fe K line generally weakens, but significant emission can persist to larger ionization parameters. The iron abundance has its greatest impact on the EW when it is less than 5 times solar. When the abundance is further increased, the line strengthens only marginally. Therefore, we conclude that Fe K lines with EWs much greater than 800 eV are unlikely to be produced by gas with a supersolar Fe abundance. These results should be useful in interpreting Fe K emission whenever it arises from optically thick fluorescence.

Ellipsometric, nuclear reaction analysis and high energy ion shadowing/blocking study of the oxidation of Fe(100)  

Science Journals Connector (OSTI)

The change in the ellipsometric parameter ? (??o) upon oxidation of various Ni and Fe single crystal surfaces has been related to absolute amounts of adsorbed oxygen, using nuclear reaction analysis (NRA). A linear relationship between ??o and oxygen uptake is found for coverages up to at least 1016 atoms/cm2. Using high energy ion scattering in combination with shadowing and blocking (HEIS-SB), the number of disordered Fe atoms on Fe(100) surfaces exposed to 02000 L O2 have been determined. Combining calibrated ellipsometry and HEIS-SB results we find that an oxide layer with average stoichiometry Fe0.950.07O forms. The oxide layer formed after exposure to 2000 L involves (5.00.5) 1015 Fe atoms/cm2 which corresponds to 4.10.4 Fe(100) monolayers.

Electronic structures and magnetic moments of Co{sub 3}FeN thin films grown by molecular beam epitaxy  

SciTech Connect

We evaluated electronic structures and magnetic moments in Co{sub 3}FeN epitaxial films on SrTiO{sub 3}(001). The experimentally obtained hard x-ray photoemission spectra of the Co{sub 3}FeN film have a good agreement with those calculated. Site averaged spin magnetic moments deduced by x-ray magnetic circular dichroism were 1.52 ?{sub B} per Co atom and 2.08 ?{sub B} per Fe atom at 100 K. They are close to those of Co{sub 4}N and Fe{sub 4}N, respectively, implying that the Co and Fe atoms randomly occupy the corner and face-centered sites in the Co{sub 3}FeN unit cell.

Preparation and characterization of PAA/PVDF membrane-immobilized Pd/Fe nanoparticles for dechlorination of trichloroacetic acid  

Science Journals Connector (OSTI)

Poly(vinylidene fluoride) (PVDF) microfiltration (MF) membrane was successfully hydrophilized by coating with a novel hydrophilic layer, which was mainly composed of polyvinyl alcohol (PVA), glutaraldehyde, and polyethylene glycol (PEG). Pd/Fe nanoparticles (NPs) were prepared and immobilized in hydrophilized polyacrylic acid (PAA)/PVDF MF membrane. The unmodified and modified PVDF MF membranes were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The membrane-supported Pd/Fe \\{NPs\\} exhibited high reactivity in the dechlorination of trichloroacetic acid (TCAA). The effects of several important parameters, including Pd content, Pd/Fe NP loading, the preservation time of Pd/Fe NP membrane system on the dechlorination of TCAA were investigated. The stability of Pd/Fe NP membrane system was tested, and the kinetics and product distribution of dechlorination of TCAA by Pd/Fe NP membrane system were discussed.

Assessment of the optimum degree of Sr{sub 3}Fe{sub 2}MoO{sub 9} electron-doping through oxygen removal: An X-ray powder diffraction and {sup 57}Fe Moessbauer spectroscopy study  

SciTech Connect

We describe the preparation and structural characterization by X-ray powder diffraction (XRPD) and Moessbauer spectroscopy of three electron-doped perovskites Sr{sub 3}Fe{sub 2}MoO{sub 9-{delta}} with Fe/Mo = 2 obtained from Sr{sub 3}Fe{sub 2}MoO{sub 9}. The compounds were synthesized by topotactic reduction with H{sub 2}/N{sub 2} (5/95) at 600, 700 and 800 {sup o}C. Above 800 {sup o}C the Fe/Mo ratio changes from Fe/Mo = 2-1 < Fe/Mo < 2. The structural refinements of the XRPD data for the reduced perovskites were carried out by the Rietveld profile analysis method. The crystal structure of these phases is cubic, space group Fm3-bar m, with cationic disorder at the two different B sites that can be populated in variable proportions by the Fe atoms. The Moessbauer spectra allowed determining the evolution of the different species formed after the treatments at different temperatures and confirm that Fe ions in the samples reduced at 600, 700 and 800 {sup o}C are only in the high-spin Fe{sup 3+} electronic state.

Electronic Structure and Fragmentation Properties of [Fe4S4(SEt)4-X(SSEt)x]2-  

SciTech Connect

A limited exposure of (n-Bu4N)2[Fe4S4(SEt)4] solutions in acetonitrile to air was found to produce a new series of [4Fe-4S] cluster complexes, [Fe4S4(SEt)4-x(SSEt)x]2- (x = 1-4), with the original SEt ligands substituted by SSEt di-sulfide ligands, which were formed due to partial decomposition of the [4Fe-4S] core in parent [Fe4S4(SEt)4]2-. The products were first observed in the experiments with an ESI-Ion Trap-TOF mass spectrometer and were further identified using high resolution FTICR (Fourier Transform Ion Cyclotron Resonance) mass spectrometer. Photoelectron spectra of the [Fe4S4(SEt)4-x(SSEt)x]2- dianions revealed that the SSEt coordination induced little change in the electronic structure of the [4Fe-4S] cluster, but the electron binding energies of [Fe4S4(SEt)4-x(SSEt)x]2- increased from 0.52 to 0.73 eV with increase in x from 0 to 4, suggesting a greater electron withdrawing ability of SSEt than -SEt. In high resolution MS/MS experiments on [Fe4S4(SEt)3(SSEt)]2-/1-, clusters with both charge states yielded fragment [Fe4S4(SEt)3]-, suggesting that SSEt could be lost either as a negatively charged ion SSEt- from the doubly charged precursor, or as a radical SSEt from the singly charged species. The biological implication of the interaction between [Fe4S4(SEt)4]2- and O2 is discussed in comparison to the air exposure of [4Fe-4S] proteins to the air.

Effect of Si interlayers on the magnetic and mechanical properties of Fe/Ge neutron polarizing multilayer mirrors  

SciTech Connect

The neutron polarizing supermirror is one of the most important optical devices for polarizing neutron beams. To meet a variety of research demands, neutron polarizing supermirrors need to display high polarization efficiencies at low external magnetic fields. Fe/Si and Fe/Ge multilayers are typically used in neutron polarizing supermirrors because the contrast in scattering length densities almost vanishes for spin-down neutrons. The Fe/Si/Ge/Si multilayer, obtained by adding thin interlayers of Si to an Fe/Ge multilayer, is effective in reducing the external field strength necessary to achieve efficient neutron polarization. To gain insight into the mechanism that controls the required external field strength for a neutron polarizing supermirror, we investigated the magnetic and mechanical properties of Fe/Si, Fe/Ge, and Fe/Si/Ge/Si multilayers. The external field strength required to achieve efficient neutron polarization was found to be proportional to the compressive film stress. The compressive stress of the Fe/Si/Ge/Si multilayer was smaller by a factor of 4.4 and 2.7 than that of Fe/Si and Fe/Ge multilayers, respectively. These measurements and analyses showed that a reduction in the compressive film stress in the Fe/Si/Ge/Si multilayer permits the use of lower external field strength to achieve efficient neutron polarization. X-ray photoelectron spectroscopic studies showed that the formation of a Ge-Si solid solution in the Ge layer may explain the marked reduction in compressive stress in the case of the Fe/Si/Ge/Si multilayer. This study confirmed that a reduction in compressive film stress is very important for a high-performance neutron polarizing supermirror.

Reduction And Immobilization Of Hexavalent Chromium By Microbially Reduced Fe-bearing Clay Minerals  

SciTech Connect

Hexavalent chromium (Cr6+) is a major contaminant in the environment. As a redox-sensitive element, the fate and toxicity of chromium is controlled by reduction-oxidation (redox) reactions. Previous research has shown the ability of structural Fe(II) in naturally present and chemically reduced clay minerals to reduce Cr6+ to Cr(III) as a way of immobilization and detoxification. However, it is still poorly known whether or not structural Fe(II) in biologically reduced clay minerals exhibits a similar reactivity and if so, what the kinetics and mechanisms of Cr6+ reduction are. The objective of this study was to determine the kinetics and possible mechanisms of Cr6+ reduction by structural Fe(II) in microbially reduced clay minerals and the nature of reduced Cr(III). Structural Fe(III) in nontronite (NAu-2), montmorillonite (SWy-2), chlorite (CCa-2), and clay-rich sediments from the Ringold Formation of the Hanford site of Washington State, USA was first bioreduced to Fe(II) by an iron-reducing bacterium Geobacter sulfurreducens with acetate as the sole electron donor and anthraquinone-2,6-disulfate (AQDS) as electron shuttle in synthetic groundwater (pH 7). Biogenic Fe(II) was then used to reduce aqueous Cr6+ at three different temperatures, 10, 20, and 30C, in order to determine the temperature dependence of the redox reaction between Cr6+ and clay-Fe(II). The results showed that nontronite and montmorillonite were most effective in reducing aqueous Cr6+ at all three temperatures. In contrast, most Fe(II) in chlorite was not reactive towards Cr6+ reduction at 10C, though at 30C there was some reduction. For all the clay minerals, the ratio of total Fe(II) oxidized to Cr6+ reduced was close to the expected stoichiometric value of 3. Characterization of the Cr-clay reaction product with scanning electron microscopy with focused ion beam and transmission electron microscopy with electron energy loss spectroscopy revealed that reduced chromium was possibly in the form of sub-nanometer Cr2O3 in association with residual clay minerals as micro-aggregates. This textural association was expected to minimize the chance of Cr(III) reoxidation upon exposure to oxidants. These results are important for our understanding of how various clay minerals may be used to reductively immobilize the heavy metal contaminant Cr in the environment.

Reduction of pertechnetate [Tc(VII)] by aqueous Fe(II) and the nature of solid phase redox products  

Science Journals Connector (OSTI)

The subsurface behaviour of 99Tc, a contaminant resulting from nuclear fuels reprocessing, is dependent on its valence (e.g., IV or VII). Abiotic reduction of soluble Tc(VII) by Fe(II)(aq) in pH 68 solutions was investigated under strictly anoxic conditions using an oxygen trap (<7.5נ10?9atmO2). The reduction kinetics were strongly pH dependent. Complete and rapid reduction of Tc(VII) to a precipitated Fe/Tc(IV) form was observed when 11?mol/L of Tc(VII) was reacted with 0.4mmol/L Fe(II) at pH 7.0 and 8.0, while no significant reduction was observed over 1 month at pH 6.0. Experiments conducted at pH 7.0 with Fe(II)(aq)=0.050.8mmol/L further revealed that Tc(VII) reduction was a combination of homogeneous and heterogeneous reaction. Heterogeneous reduction predominated after approximately 0.01mmol/L of Fe(II) was oxidized. The heterogeneous reaction was more rapid, and was catalyzed by Fe(II) that adsorbed to the Fe/Tc(IV) redox product. Wet chemical and FeX-ray absorption near edge spectroscopy measurements (XANES) showed that Fe(II) and Fe(III) were present in the Fe/Tc(IV) redox products after reaction termination. 57Fe-Mssbauer, extended X-ray adsorption fine structure (EXAFS), and transmission electron microscopy (TEM) measurements revealed that the Fe/Tc(IV) solid phase was poorly ordered and dominated by Fe(II)-containing ferrihydrite with minor magnetite. Tc(IV) exhibited homogeneous spatial distribution within the precipitates. According to Tc-EXAFS measurements and structural modeling, its molecular environment was consistent with an octahedral Tc(IV) dimer bound in bidentate edge-sharing mode to octahedral Fe(III) associated with surface or vacancy sites in ferrihydrite. The precipitate maintained Tc(IV)aq concentrations that were slightly below those in equilibrium with amorphous Tc(IV)O2nH2O(s). The oxidation rate of sorbed Tc(IV) in the Fe/Tc precipitate was considerably slower than Tc(IV)O2nH2O(s) as a result of its intraparticle/intragrain residence. Precipitates of this nature may form in anoxic sediments or groundwaters, and the intraparticle residence of sorbed/precipitated Tc(IV) may limit 99Tc remobilization upon the return of oxidizing conditions.

Magnetic excitations and anomalous spin wave broadening in multiferroic FeV2O4  

SciTech Connect

FeV2O4 is found to show three structural transitions and successive paramagnetic(PM)- collinear ferrimagnetic(CFI)-nocollinear ferrimagnetic(NCFI) magnetic transitions. The tetragonal- orthorhombic structural transition associated with PM-CFI transition is accompanied by the ap- pearance of an energy gap with a high magnitude in the magnetic excitation spectrum, which is a consequence of the strong spin-orbital coupling induced anisotropy at Fe2+ A site. The comparison of Fe spin waves at CFI and noncollinear ferrimagnetic/ferroelectric phases shows no signicant spin frustration of Fe2+ spins at A site, suggesting A-site Fe2+ spins may not play a main role in the appearance of the ferroelectricity. Spin wave damping shows a rapid increase when NCFI transforms to CFI phase, indicating a possible V3+ spin uctuations at B site prior to their true canting in the NCFI phase. The spin wave broadening is also observed at the zone boundary without the spin wave softening, which is discussed in terms of the eect of magnon-phonon coupling. Understanding the

IMPLICATIONS OF INFALLING Fe II-EMITTING CLOUDS IN ACTIVE GALACTIC NUCLEI: ANISOTROPIC PROPERTIES  

SciTech Connect

We investigate consequences of the discovery that Fe II emission in quasars, one of the spectroscopic signatures of 'Eigenvector 1', may originate in infalling clouds. Eigenvector 1 correlates with the Eddington ratio L/L {sub Edd} so that Fe II/Hbeta increases as L/L {sub Edd} increases. We show that the 'force multiplier', the ratio of gas opacity to electron scattering opacity, is approx10{sup 3}-10{sup 4} in Fe II-emitting gas. Such gas would be accelerated away from the central object if the radiation force is able to act on the entire cloud. As had previously been deduced, infall requires that the clouds have large column densities so that a substantial amount of shielded gas is present. The critical column density required for infall to occur depends on L/L {sub Edd}, establishing a link between Eigenvector 1 and the Fe II/Hbeta ratio. We see predominantly the shielded face of the infalling clouds rather than the symmetric distribution of emitters that has been assumed. The Fe II spectrum emitted by the shielded face is in good agreement with observations thus solving several long-standing mysteries in quasar emission lines.

Electrochemical investigations on amorphous Fe-base alloys for alkaline water electrolysis  

Science Journals Connector (OSTI)

Abstract In this work different amorphous melt-spun Fe-alloys (Fe82B18, Fe80Si10B10, Fe60Co20Si10B10) were investigated as cathode materials for the alkaline electrolysis of water. In particular, the influence of cobalt as well as the metalloids boron and silicon on the activity for the hydrogen evolution reaction (HER) was studied in 1M KOH at 298K using cyclic voltammetric, galvanostatic and polarization techniques. The electrocatalytic activity was evaluated in the view of the overpotential. It was found that cyclic voltammetric techniques can be used to activate the melt-spun Fe-alloys strongly. Different cyclic voltammetric activation procedures are discussed and the influence of the sweep rate and the potential window on the HER activity was elucidated. The experimental data indicate that the addition of metalloids and, most importantly, of cobalt improves the HER activity of the materials. Thus, the overpotential can be reduced by 200mV compared to polycrystalline Ni.

Fe/Si(001) Ferromagnetic Layers: Reactivity, Local Atomic Structure and Magnetism  

SciTech Connect

Ultrathin ferromagnetic Fe layers on Si(001) have recently been synthesized using the molecular beam epitaxy (MBE) technique, and their structural and magnetic properties, as well as their interface reactivity have been investigated. The study was undertaken as function of the amount of Fe deposited and of substrate temperature. The interface reactivity was characterized by Auger electron spectroscopy (AES). The surface structure was characterized by low-energy electron diffraction (LEED). The magnetism was investigated by magneto-optical Kerr effect (MOKE). A higher deposition temperature stabilizes a better surface ordering, but it also enhances Fe and Si interdiffusion and it therefore decreases the magnetism. Despite the rapid disappearance of the long range order with Fe deposition at room temperature, the material exhibits a significant uniaxial in-plane magnetic anisotropy. For the Fe deposition performed at high temperature (500 deg. C), a weak ferromagnetism is still observed, with saturation magnetization of about 10% of the value obtained previously. MOKE studies allowed inferring the main properties of the distinct formed layers.

Microstructural and magnetic characterizations of CoFeCu electrodeposited in self-assembled mesoporous silicon  

Science Journals Connector (OSTI)

Abstract Self-assembled mesoporous silicon with quasi-regular pore arrangements has been fabricated by the electrochemical anodization process in hydrofluoric acid solution. CoFeCu was electrodeposited in this structure from a bath containing sodium acetate as a complexing agent with a pH value of 5. The effect of current density on the morphology, the structure and the magnetic properties of CoFeCu deposit was studied by SEM, EDS, DRX and VSM. It has been shown that the morphology and structure of samples were strongly influenced by the current density and etching duration. The micrographs show the vertical and branched nanowires and also a discontinuous growth of wires. Further, the growth of a thick layer from the grain boundaries of released CoFeCu wires is produced. The magnetic hysteresis loops demonstrate that the CoFeCu nanowires exhibit easy magnetic axis perpendicular to the PS channels axis when the current density varied from 3 to 10mA/cm2. Nevertheless, they reveal a no magnetic anisotropy of CoFeCu nanostructures deposited only in the outside of porous silicon, probably due to the vanishing the shape anisotropy.

Easy axis alignment of chemically partially ordered FePt nanoparticles  

SciTech Connect

Partially ordered Fe{sub 53}Pt{sub 47} nanoparticles with size around 8 nm were prepared by the simultaneous decomposition of iron pentacarbonyl and platinum acetylacetonate. The high boiling point chemical, hexadecylamine, was used as a solvent, and 1-adamantanecarboxylic acid was used as a stabilizer. X-ray diffraction measurements reveal that as-made FePt particles were partially transformed into the ordered L1{sub 0} phase with some weak superlattice peaks. The room-temperature hysteresis loop and remanence curve suggest a broad distribution of anisotropies in the partially ordered particles. By coating the partially ordered FePt nanoparticles with a polyvinylchloride polymer binder, the particles could be re-dispersed in cyclohexanone. Furthermore, the easy axis of the particles coated with the polyvinylchloride polymer binder could be aligned under an external field. Easy axis alignment was confirmed from both alternating gradient magnetometer and x-ray diffraction measurements.

A Ni-Fe Layered Double Hydroxide-Carbon Nanotube Complex for Water Oxidation  

E-Print Network (OSTI)

Highly active, durable and cost-effective electrocatalysts for water oxidation to evolve oxygen gas hold a key to a range of renewable energy solutions including water splitting and rechargeable metal-air batteries. Here, we report the synthesis of ultrathin nickel iron layered double hydroxide nanoplates on mildly oxidized multi-walled carbon nanotubes. Incorporation of Fe into the nickel hydroxide induced the formation of NiFe-layered double hydroxide. The nanoplates were covalently attached to a network of nanotubes, affording excellent electrical wiring to the nanoplates. The ultra-thin Ni-Fe layered double hydroxide nanoplates/carbon nanotube complex was found to exhibit unusually high electro-catalytic activity and stability for oxygen evolution and outperformed commercial precious metal Ir catalysts.

Structure determination of thin CoFe films by anomalous x-ray diffraction  

SciTech Connect

This work reports on the investigation of structure-property relationships in thin CoFe films grown on MgO. Because of the very similar scattering factors of Fe and Co, it is not possible to distinguish the random A2 (W-type) structure from the ordered B2 (CsCl-type) structure with commonly used x-ray sources. Synchrotron radiation based anomalous x-ray diffraction overcomes this problem. It is shown that as grown thin films and 300 K post annealed films exhibit the A2 structure with a random distribution of Co and Fe. In contrast, films annealed at 400 K adopt the ordered B2 structure.

Antiferromagnetic spin excitations in single crystals of nonsuperconducting Li$_{1-x}$FeAs  

SciTech Connect

We use neutron scattering to determine spin excitations in single crystals of nonsuperconducting Li1 xFeAs throughout the Brillouin zone. Although angle resolved photoemission experiments and local density approximation calculations suggest poor Fermi surface nesting conditions for antiferromagnetic (AF) order, spin excitations in Li1 xFeAs occur at the AF wave vectors Q = (1,0) at low energies, but move to wave vectors Q = ( 0.5, 0.5) near the zone boundary with a total magnetic bandwidth comparable to that of BaFe2As2. These results reveal that AF spin excitations still dominate the low-energy physics of these materials and suggest both itinerancy and strong electron-electron correlations are essential to understand the measured magnetic excitations.

Surface transport properties of Fe-based superconductors: The influence of degradation and inhomogeneity  

SciTech Connect

Surface properties of Co-doped BaFe{sub 2}As{sub 2} epitaxial superconducting thin films were inspected by X-ray photoelectron spectroscopy, scanning spreading resistance microscopy (SSRM), and point contact spectroscopy (PCS). It has been shown that surface of Fe-based superconductors degrades rapidly if being exposed to air, what results in suppression of gap-like structure on PCS spectra. Moreover, SSRM measurements revealed inhomogeneous surface conductivity, what is consistent with strong dependence of PCS spectra on contact position. Presented results suggest that fresh surface and small probing area should be assured for surface sensitive measurements like PCS to obtain intrinsic properties of Fe-based superconductors.

Investigation of spin phonon coupling in BiFeO{sub 3} based system by Fourier transform infrared spectroscopy  

SciTech Connect

In the present work, the low temperature infrared absorption spectra of BiFeO{sub 3} (BFO) are measured to explore the spin-phonon coupling in this compound. At 303?K, 4 weak transverse optic (TO) IR-active phonon modes E(TO6), E(TO7), E(TO8), and E(TO9) are observed. First two modes are corresponded to the Fe{sup 3+} cations caused by the internal vibration of FeO{sub 6} octahedra, E(TO8) is correlated to Fe-O bending vibration and E(TO9) is assigned to Fe-O stretching vibrations, respectively. At 213?K, two new modes E(TO5) and A1(TO3) are emerging out. Both are assigned to Fe{sup 3+} cations caused by the internal vibration of FeO{sub 6} octahedra. These modes get stronger and stronger with lowering the temperature due to the lattice contraction. When the temperatures decreases to T???213?K, an additional phonon mode is start appearing at around 638?cm{sup ?1} suggesting local lattice distortion of FeO{sub 6} octahedra. The temperature is corresponding with the FC and zero field cooled bifurcation temperature, which is related to the onset of spin glass behaviour. The occurrence of this additional phonon mode at this particular temperature suggests that there is strong spin-phonon coupling in BFO. This argument is further supported by the temperature dependence of this additional phonon peak. It shows anomaly around 124?K, which is related to spin reorientation of Fe{sup 3+} ions. This result clearly indicates that spin glass state and spin reorientation of Fe{sup 3+} is accompanied with the local structure distortion of FeO{sub 6} octahedra, providing evidence for the strong spin-phonon coupling in the BFO.

Cation-Bonding and Protonation of the Fe[subscript 4]-Square Cluster  

SciTech Connect

The synthesis and characterization of discrete, molecular iron-oxo clusters is pursued in the interest of molecular magnets, bioinspired materials and models for the geochemical aqueous-mineral interface. Iron-oxo clusters are challenging to synthesize in water, due to the extremely acidic and reactive nature of dissolved iron species, and thus require chelating ligands to passivate and neutralize the cluster surface. The 2-hydroxy-1,3-N,N,N',N'-diamino-propanetetraacetic acid (HPDTA) ligand has been used to isolate several Al and Fe cluster geometries, including the square clusters Fe{sub 4}(HPDTA){sub 2} and Al{sub 4}(HPDTA){sub 2}. While prior reports on the Fe{sub 4}(HPDTA){sub 2} cluster have focused on the magnetic properties, no solution characterization has been carried out. Using electrospray ionization mass-spectrometry (ESI-MS) we show this anionic Fe{sub 4}(HPDTA){sub 2} cluster can be dissolved intact in water, and recrystallized with virtually any metal as a countercation. The bonding of the metal cation to the square face of the cluster trends with ionic radii of the cations, as shown by structural characterization of Fe{sub 4}(HPDTA){sub 2} with Li{sup +}, Na{sup +}, Cs{sup +}, Mg{sup 2+}, Ba{sup 2+}, La{sup 3+}, Eu{sup 3+}, and Zn{sup 2+}. This trend is similar to that observed for association of cations on metal oxide surfaces in the environment. Furthermore, protonation of the bridging oxo ligands of this series of Fe{sub 4}(HPDTA){sub 2} clusters is variable (0, 1, or 2 protons), and structures as a function of protonation is discussed. This paper, largely structural in nature, sets the foundation for future aqueous phase studies of iron-oxo molecular clusters as models for the oxide-water interface in the natural aqueous environment.

Theoretical description of the high-field susceptibility of magnetically ordered transition metal systems with applications to Fe, Co, Ni, and Fe1?xCox  

Science Journals Connector (OSTI)

A theoretical description of the high-field susceptibility of magnetically ordered transition metal systems is presented that is based on linear response theory formulated using the Greens function technique. The approach allows to treat all spin and orbital contributions in a consistent way on the same footing. In contrast to previous work, the Landau susceptibility is included and spin-orbit induced contributions to the susceptibility are accessible by using a fully relativistic formulation. As an application of our approach, results obtained for the ferromagnetic transition metals Fe, Co, and Ni, as well as for the alloy system Fe1?xCox, are presented. These are discussed and compared to corresponding experimental data.

Society Evaluation of point defect concentrations in B2-FeAl intermetallic compound  

E-Print Network (OSTI)

Thermal defects are studied for three compositions (49, 50 and 52 at.%Fe) of the intermetallic compound FeAl with B2 structure. Magnetic measurements are used to determine the thermal defect concentrations. These concentrations are determined from fitting the experimental curves of magnetic susceptibility, obtained during an isochronal annealing after a quench. Next we have evaluated theoretically the concentrations of different point defects that exist in this compound. The used model is based in the Bragg-Williams approximation assuming the nearest-neighbour interaction. The calculated concentrations describe well the experimental values. I.

Silicon's role in determining swelling in neutron-irradiated Fe-Cr-Ni-Si alloys  

SciTech Connect

Two silicon-modified alloy series, one based on Fe-15Cr-20Ni and another based on Fe-15Cr-25Ni were irradiated at target temperatures between 399 and 649{degree}C in EBR-II. The influence of silicon on swelling is more complex than previously envisioned and indicates that silicon plays two or more competing roles while in solution. Radiation-induced formation of {gamma}{prime} (Ni{sub 3}Si) precipitates is dependent on silicon and nickel content, as well as temperature. Precipitation of {gamma}{prime} appears to play only a minor role in void formation.

Room-Temperature Multiferroic Hexagonal LuFeO3 Films  

The crystal and magnetic structures of single-crystalline hexagonal LuFeO3 films have been studied using x-ray, electron, and neutron diffraction methods. The polar structure of these films are found to persist up to 1050 K; and the switchability of the polar behavior is observed at room temperature, indicating ferroelectricity. An antiferromagnetic order was shown to occur below 440 K, followed by a spin reorientation resulting in a weak ferromagnetic order below 130 K. This observation of coexisting multiple ferroic orders demonstrates that hexagonal LuFeO3 films are room-temperature multiferroics.

In-situ magnetization of NdFeB magnets for permanent magnet machines  

SciTech Connect

In-situ magnetizers are needed to facilitate the assembly of permanent magnet machines and to remagnetize the magnets after weakening due to a fault condition. The air-core magnetizer in association with the silicon steel lamination structure of the rotor has advantages over its iron-core counterpart. This novel method has been used to magnetize the NdFeB magnets in a 30-hp permanent magnet synchronous motor. The magnetizing capability for different magnetizer geometries was investigated for the magnetization of NdFeB material. The design, testing, and operation of this magnetizer are reported in this paper.

Effect of doping Fe and Si on electronic structure and optical Properties of CdS  

Science Journals Connector (OSTI)

The geometrical structure, electronic properties and optical properties of CdS and M@CdS (M=Fe, Si) were studied systemically with first principles density functional theory. The band structure and density of states have been calculated to analyze the effect of the doping Fe and Si elements on the electronic properties and magnetic properties of CdS. The results show that all the conductive, magnetic and optical properties of CdS are changed by the doped elements. Both obvious and insignificant changes are found in some cases, which provide helpful guide for preparing doped CdS materials.

Nano-magnetism of magnetostriction in Fe{sub 35}Co{sub 65}  

SciTech Connect

The nature of the large magnetostriction in body-centered Fe-based solid solutions has been widely discussed in the literature. Here, we use a combination of magnetostriction, magnetization, torque, and transmission electron microscopy measurements of specially annealed Co{sub 65}Fe{sub 35} to show that the magnetostriction is caused by coherent uniaxial nano-precipitates. We show further that these nano-precipitates lower the magnetocrystalline anisotropy in these alloys to K{sub 1}?=??2.16??10{sup 4}?J/m{sup 3}.

Neutron scattering investigation of the magnetic order in single crystalline BaFe2As2  

SciTech Connect

The magnetic structure of BaFe{sub 2}As{sub 2} was determined from polycrystalline neutron diffraction measurements soon after the ThCr{sub 2}Si{sub 2}-type FeAs-based superconductors were discovered. Both the moment direction and the in-plane antiferromagnetic wavevector are along the longer a-axis of the orthorhombic unit cell. There is only one combined magnetostructural transition at {approx}140 K. However, a later single-crystal neutron diffraction work reported contradicting results. Here, we show neutron diffraction results from a single-crystal sample, grown by a self-flux method, that support the original polycrystalline work.

Crystal-field effects of Sm3+ ions in Sm2Fe17Nx  

Science Journals Connector (OSTI)

Using only two crystalline electric-field parameters A20 and A40 and the Sm-Fe exchange field Hex, the magnetic-anisotropy behavior of the Sm ion in Sm2Fe17Nx is described. It is shown that a field-induced noncollinear coupling between the spin and orbital moments of the Sm ion takes place during the magnetization process when the external field is applied along the hard axis. This noncollinear coupling causes a very different magnetization process of the Sm moment at T=0 and 300 K.

Sediment-water exchange of Mn, Fe, Ni and Zn in Galveston Bay, Texas  

Science Journals Connector (OSTI)

In-situ benthic flux studies were conducted at three stations in Upper Galveston Bay twice during March 1996 to directly measure release rates of dissolved Mn, Fe, Ni and Zn from the sediments. Results showed reproducible increases with time in both replicate light and lightdark benthic chambers, resulting in average fluxes of ?1200780, ?1712, ?1.60.6 and ?2.40.79 ?mol m?2 day?1 for Mn, Fe, Ni and Zn, respectively. Sediment cores collected during 19941996 showed that surficial pore water concentrations were elevated compared to overlying water column concentrations, suggesting diffusive release from the sediments. Diffusive flux estimates of Mn and Zn agreed in direction with chamber fluxes measured on the same date, but only accounted for 538% of the measured flux. Diffusive fluxes of Fe agreed with measured fluxes at the near Trinity River station but overestimated actual release in the mid and outer Trinity Bay regions, possibly due to inaccurate determination of the Fe pore water gradients or rapid oxidation processes in the overlying water at these stations. In general, measured fluxes of Mn and Ni were higher in the mid Trinity Bay region and suggested a mechanism for the elevated trace metal concentrations previously reported for this region of Galveston Bay. However, the fluxes of Fe were highest in close proximity to the Trinity River, supporting the elevated Fe concentrations measured in this region during this and other studies, and decreased towards middle and outer Trinity Bay. Trace metal turnover times were between 0.1 and 1.2 days for Mn, between 1.3 and 4.6 days for Fe, and between 27 and 100 days for Ni and 1220 days Zn, and were considerably shorter than the average Trinity Bay water residence time (1.5 years) for this period. Comparing area averaged benthic inputs to Trinity River inputs shows the sediments to be a significant source of trace metals to Galveston Bay. However, while benthic inputs of trace metals were measured, water column concentrations remained low despite rapid turnover times for Mn and Fe, suggesting removal of these metals from the water column after release from the sediments.

Magnetic anisotropy engineering: Single-crystalline Fe films on ion eroded ripple surfaces  

SciTech Connect

We present a method to preselect the direction of an induced in-plane uniaxial magnetic anisotropy (UMA) in thin single-crystalline Fe films on MgO(001). Ion beam irradiation is used to modulate the MgO(001) surface with periodic ripples on the nanoscale. The ripple direction determines the orientation of the UMA, whereas the intrinsic cubic anisotropy of the Fe film is not affected. Thus, it is possible to superimpose an in-plane UMA with a precision of a few degrees - a level of control not reported so far that can be relevant for example in spintronics.

LaFeO{sub 3} nanospheres have been successively synthesized via hydrothermal method. Structural, morphological and optical properties of the prepared nanopowder were analyzed by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and UVVis absorption spectroscopy. The UVVis shows strong absorption at 475 nm which has excellent visible light absorption ability. Band gap energy of the prepared nanosphere was found to be 2.60 eV. The results indicate that the LaFeO{sub 3} nanospheres prepared by this method could be a kind of photocatalytic material.

Uniaxial pressure effect on structural and magnetic phase transitions in NaFeAs and its comparison with as-grown and annealed BaFe2As2  

SciTech Connect

We use neutron scattering to study the effect of uniaxial pressure on the tetragonal-toorthorhombic structural (Ts) and paramagnetic-to-antiferromagnetic (TN) phase transitions in NaFeAs and compare the outcome with similar measurements on as-grown and annealed BaFe2As2. In previous work on as-grown BaFe2As2, uniaxial pressure necessary to detwin the sample was found to induce a significant increase in zero pressure TN and Ts. However, we find that similar uniaxial pressure used to detwin NaFeAs and annealed BaFe2As2 has a very small effect on their TN and Ts. Since transport measurements on these samples still reveal resistivity anisotropy above TN and Ts, we conclude that such anisotropy cannot be due to uniaxial strain induced TN and Ts shifts, but must arise from intrinsic electronic anisotropy in these materials.

Science Journals Connector (OSTI)

A Fe2O3 nanoparticle/carbon aerogel composite (Fe2O3/CA) is prepared from a carbon aerogel prepared by a solgel process by a simple soaking in a Fe(NO3)3 solution and subsequent heat treatment at 600C. Thermal gravimetric analysis, X-ray diffraction, scanning and transmission electron microscopy, energy dispersive X-ray analysis and X-ray photoelectron spectroscopy are used to characterize the products. The electrochemical performance of samples with different Fe2O3 content is evaluated. The optimal sample Fe2O3/CA-60 exhibits a good capacity retention of 916 and 617mAhg?1 for the 1st and 100th cycle, respectively, which is much better than that of pure Fe2O3 and CA. The improved cycling performance, specific capacity and rate capability of Fe2O3/CA is mainly attributed to the synergistic effects of the nanoporous network skeleton of CA and the uniformly dispersed Fe2O3 nanoparticles.
