Abstract

A single-step method for the preparation of metastable epsilon-Fe3N nanoparticles by combustion of reactive gels containing iron nitrate (Fe(NO3)(3)) and hexamethylenetetramine (C6H12N4) in an inert atmosphere is reported. The results of Fourier transform infrared spectroscopy (FTIR) and thermal analysis coupled with dynamic mass spectrometry revealed that the exothermic decomposition of a coordination complex formed between Fe(NO3)(3) and HMTA is responsible for the formation of epsilon-Fe3N nanoscale particles with sizes of 5-15 nm. The magnetic properties between 5 and 350 K are characterized using a superconducting quantum interference device (SQUID) magnetometer, revealing a ferromagnetic behavior with a low-temperature magnetic moment of 1.09 mu(B)/Fe, high room temperature saturation magnetization (similar to 80 emu/g), and low remanent magnetization (similar to 15 emu/g). The obtained value for the Curie temperature of , similar to 522 K is close to that (similar to 575 K) for bulk epsilon-Fe3N reported in the literature.

Room temperature ferroelectric and magnetic investigations and detailed phase analysis of Aurivillius phase Bi{sub 5}Ti{sub 3}Fe{sub 0.7}Co{sub 0.3}O{sub 15} thin films

Journal Article Keeney, Lynette ; Kulkarni, Santosh ; Deepak, Nitin ; ... - Journal of Applied Physics

Aurivillius phase Bi{sub 5}Ti{sub 3}Fe{sub 0.7}Co{sub 0.3}O{sub 15} (BTF7C3O) thin films on {alpha}-quartz substrates were fabricated by a chemical solution deposition method and the room temperature ferroelectric and magnetic properties of this candidate multiferroic were compared with those of thin films of Mn{sup 3+} substituted, Bi{sub 5}Ti{sub 3}Fe{sub 0.7}Mn{sub 0.3}O{sub 15} (BTF7M3O). Vertical and lateral piezoresponse force microscopy (PFM) measurements of the films conclusively demonstrate that BTF7C3O and BTF7M3O thin films are piezoelectric and ferroelectric at room temperature, with the major polarization vector in the lateral plane of the films. No net magnetization was observed for the in-plane superconducting quantummore »« less

Preparation and characterization of shuttle-like {alpha}-Fe{sub 2}O{sub 3} nanoparticles by supermolecular template

Journal Article Xianming, Liu ; Graduate School of Chinese Academy of Sciences, Beijing 100039 ; Shaoyun, Fu ; ... - Journal of Solid State Chemistry

Shuttle-like {alpha}-Fe{sub 2}O{sub 3} nanoparticles have been successfully synthesized via a new soft-template route using polyethylene glycol (PEG) as polymer, cetyltrimethylammonium bromide (CTAB) as surfactant and FeCl{sub 3}.6H{sub 2}O as iron source materials. Meanwhile, spherical {alpha}-Fe{sub 2}O{sub 3} nanoparticles are also fabricated under the similar conditions without surfactant and polymer. The resultant products are characterized by means of thermalgravimetric analysis (TGA), powder X-ray diffraction (XRD), infrared (IR) spectroscopy, transmission electron micrograph (TEM), X-ray photoelectron spectra (XPS) and magnetization measurements. The homogeneous {alpha}-Fe{sub 2}O{sub 3} nanoparticles with shuttle-like shape have an average length of 120 nm and a mean diameter ofmore »« less

Magnetic stability of He+ ion irradiated FeO+Fe3N granular films

Journal Article Sundararajan, J A ; Zhang, Dongtao ; Qiang, You ; ... - Journal of Applied Physics, 109(7):07E324: 1 - 3

Ion irradiation effects on the magnetic properties of FeO/Fe3N (Iron oxide/Iron Nitride) nanoparticles are investigated in this study. The FeO/Fe3N nanoparticles were prepared using a nanocluster deposition system. The x-ray diffraction data confirms the presence of FeO and Fe3N compounds in the prepared nanoparticles. The saturation magnetization (30 emu/g), coercivity (87.9 Oe) and remanence (3.2 emu/g) of these nanoparticles remain unaltered after irradiation with 2 MeV He+ ions to a fluence of 3E15 ions/cm2 at room temperature, indicating that the magnetic properties of these nanoparticles are not affected in a highly radioactive environment. This unique property of the magnetic stabilitymore »« less

Journal Article Craciun, F. ; Dimitriu, E. ; Grigoras, M. ; ... - Journal of Applied Physics

The emergence of magnetic properties and quadratic magnetoelectric coupling in a material with outstanding ferroelectric properties has been pursued. Thus, the multiferroicity driven by the substitution of rare earth R{sup 3+} ions (R = Sm, Nd) on the A-site of PbTiO{sub 3} perovskite ceramics has been investigated. In some samples, a transition element with large ionic radius, like Fe{sup 2+}, has been also added on the A site. Polycrystalline ceramic samples with composition (Pb{sub 1-3x/2-y}R{sub x}Fe{sub y}) (Ti{sub 0.98}Mn{sub 0.02})O{sub 3} (R = Sm; x = 0.08, y = 0.035) and (Pb{sub 1−3x/2}R{sub x})(Ti{sub 0.98}Mn{sub 0.02})O{sub 3} (R = Nd, x = 0.08) have been prepared by conventional solid state ceramic processing,more »« less

Magnetic viscosity studies in hard magnetic materials

Journal Article Singleton, E W ; Hadjipanayis, G C - Journal of Applied Physics; (USA)

The magnetic viscosity behavior has been studied in several hard magnets with different magnetization reversal mechanisms including barium ferrite powders, Cu-Mn-Al, ferrite magnets, Nd-Fe-B, and SmCo{sub 5}, Sm{sub 2}(Co,Fe,Cu,Zr){sub 17}. The measurements were made with a vibrating sample magnetometer for times up to 60 s and a SQUID magnetometer for longer times in the range of 60--2300 s. For most of the samples the magnetization was found to vary logarithmically with time. The field and temperature dependence of the magnetic viscosity coefficient {ital S} was studied. Here, {ital S} was found to vary with the applied field and it usuallymore »« less
