Title: Crystal-structure and Mossbauer studies of Li{sub 1.746}Nd{sub 4.494}FeO{sub 9.493}

Abstract

The Li{sub 1.746}Nd{sub 4.494}FeO{sub 9.493} (LNF) ternary phase, located in the Li{sub 2}O-rich part of the Li{sub 2}O-Nd{sub 2}O{sub 3}-Fe{sub 2}O{sub 3} system, crystallizes with a cubic unit cell of dimension a=11.9763(3)A and the space group Im3m. Refinement on F resulted in R=1.9%. The structure is comprised of a network of corners, edges and faces sharing the coordination polyhedra of neodymium. In between this skeleton the regular octahedra of oxygen-coordinated iron and trigonal prisms of lithium are located. The Mossbauer spectra revealed the presence of Fe{sup 3+}, Fe{sup 4+} and Fe{sup 5+} ions distributed on two symmetry-independent lattice positions.

  • Bi{sub 0.8}A{sub 0.2}FeO{sub 3} (A = La, Ca, Sr, Ba) multiferroics were studied using x-ray, neutron diffraction and magnetization techniques. All the samples crystallized in rhombohedral structure with space group R3c. The compounds exhibit antiferromagnetic (AFM) ordering at 300 K and no evidence of further structural or magnetic transition was observed on lowering of temperature below it. The magnetic structure of these substituted compounds are found to be collinear G-type AFM structure as against the non collinear incommensurate magnetic structure reported in the case of parent compound. The moments on Fe at 6 K are aligned along the a-axis inmore » the case of Ca-doped sample. With increase in the ionic radii of dopant, the moments are found to be aligned in the ac plane and the angle of tilt away from the a-axis increases. The observed change in the magnetic structure with substitution is attributed to the intrinsic structural distortion as evidenced by the change in the bond angle (Fe-O-Fe) and bond distances (Bi-O, Fe-O). It has been found that heterovalent substitution A{sup 2+} results in the formation of oxygen vacancies in the parent lattices as the possibility of Fe{sup 4+} ruled out by M√∂ssbauer spectra recorded at room temperature. Higher value of remnant magnetization (0.4187 emu/g) and coercivity (4.7554kOe) is observed in Bi{sub 0.8}Ba{sub 0.2}FeO{sub 3} sample in comparison to other substituted samples revealing a strong correlation between ionic radii and magnetization.« less
  • Charge transfer type Nd{sub 1/3}Sr{sub 2/3}FeO{sub 3} was synthesized and its magnetic properties were investigated by neutron diffraction and Mossbauer spectroscopy at various temperatures ranging from 4.2 K to room temperature. The powder neutron diffraction shows magnetic ordering structures. The Nd{sub 1/3}Sr{sub 2/3}FeO{sub 3} with small lattice distortion underwent a charge ordering (CO) phase transition at and below T{sub CO}=163K corresponding to a sequence of Fe{sup +3}Fe{sup +3}Fe{sup +5}Fe{sup +3}Fe{sup +3}Fe{sup +5} aligned along the z direction of rhombohedral, as well as canted antiferromagnetic spin ordering. The spin rotation resulting from helical spin of Nd was observed at and belowmore » 25 K. At 4.2 K, the electric quadrupole splittings for Fe{sup 3+} and Fe{sup 5+} are 0.06 and 0.15 (mm/s) which were changed to {minus}0.06 and {minus}0.02 (mm/s) at and above 20 K. It is evidence of spin rotation in Nd{sub 1/3}Sr{sub 2/3}FeO{sub 3}. {copyright} 2001 American Institute of Physics.« less
  • Systems of solid solutions Bi{sub 1-x}Ca{sub x}FeO{sub 3} (I) and Bi{sub 1-x}CaxFeO{sub 1-x}Ti{sub x}O{sub 3} (II) have been obtained and their properties have been studied using neutronography and Moessbauer spectroscopy; magnetization and permittivity have been measured. It is shown that an increase in the concentration of calcium ions in system I for x > 0.2 changes rhombohedral distortions of a unit cell (space group R3c) to tetragonal distortions (space group I4/mcm), while rhombohedral distortions in system II for x > 0.2 are replaced by orthorhombic distortions (space group Pnma). Analysis of the crystal structure has revealed strong anisotropy in vibrationsmore » of Bi and O ions in system I compounds. Systems I and II are characterized by G-type antiferromagnetic ordering of magnetic moments. In system II, spontaneous magnetization associated with the Dzyaloshinskii-Moriya interaction has been detected. According to Moessbauer spectroscopy data, iron ions in compounds I and II are in the trivalent state and charge compensation occurs due to the formation of oxygen vacancies. The permittivity increases with the calcium concentration.« less
  • Existing X-ray diffraction data (Mammono and Sienko, 1968) and neutron diffraction data (Chieux, Sienko, and DeBaecker, 1975) on the solid lithium-ammonia compounds have had to be reevaluated in the light of recent magnetic studies which indicate absence of the 82 K solid-solid transition in the deuterated compound. X-ray reflections observed at 77 K, which were previously interpreted as a mixture of hexagonal and body-centered-cubic phases, are better indexed as a single body-centered-cubic phase. Solid-phase II of Li(NH/sub 3/)/sub 4/, stable below 82 K, appears to belong to space group I43d, a = 14.93 angstrom, with 16 lithium atoms and 16more » nitrogen atoms on Wyckoff position c and 48 nitrogens on Wyckoff position e. The same structure holds for Li(ND/sub 3/)/sub 4/. Below 25 K, extra reflections appear, corresponding to formation of a superstructure with period 2a. This coincides with onset of what appears to be antiferromagnetic ordering below this temperature.« less
  • A second form of the literature-known layered weak ferromagnet Fe[(CH{sub 3}PO{sub 3})(H{sub 2}O)] has been isolated. The crystal structure determination of this new form (2) has been carried out at T=300, 200 and 130K. It crystallizes in the orthorhombic space group Pmn2{sub 1}: a=5.7177(11), b=8.8093(18), c=4.8154(10)A, while form (1) crystallizes in the space group Pna2{sub 1}: a=17.58(2), b=4.814(1), c=5.719(1)A. Moessbauer spectroscopy on form (2) has been performed in the temperature range 4-300K; and, at T{approx}160K, a drastic change in the quadrupole splitting ({delta}E) and a broadening of the doublet components is noticed. But surprisingly, on cooling the crystal, no structuralmore » change is observed, which could account for the increase in {delta}E. Below T=25K, {sup 57}Fe spectra transform into hyperfine splitting patterns which reveal a magnetically ordered state in agreement with the results of earlier magnetic susceptibility studies.« less
