Structural and magnetic study of RFe{<_0.5}V{<_0.5}O{<_3} (R = Y, Eu, Nd, La) perovskite compounds.
- Materials Science Division
B-site disordered RFe{sub 0.5}V{sub 0.5}O{sub 3} compounds, with R=La, Nd, Eu and Y, have been prepared by solid-state reaction technique and their structures and magnetic properties have been investigated through X-ray powder diffraction, time-of-flight neutron powder diffraction and magnetization measurements at temperatures ranging from 5 to 700 K. The four compounds can be described as distorted perovskites with space group symmetry Pbnm and a{sup +}b{sup -}b{sup -} tilt system. The studied compounds also show antiferromagnetic ordering with Neel temperatures of 299, 304, 304, and 335 K respectively. The magnetic structures of R=La, Nd and Y compounds were determined from the neutron powder diffraction as Gz with observed magnetic moments of 2.55, 2.54 and 2.69 {mu}{sub B} at 30, 40 and 40 K, respectively.
