Magnetization Evolution with the Doping Element in Double Perovskite

Abstract:

Double perovskite (Sr1.85Ln0.15)FeMoO6 (Ln=Sr, La, Ce, Pr, Nd, Sm and Eu) have been prepared by solid-state reaction. Crystal structure investigation shows that all the samples are of single phase and belong to the I4/m space group. Saturation magnetization of the compounds at 5 K cannot be explained simply by ferrimagnetic model (FIM). However, the saturation magnetization at 100 K of the doped compounds exhibits a linear decrease with the increase of the anti-site defect concentration. Comparison of the saturation magnetization of the compounds at 5 K and 100 K suggests that at 5 K the magnetic moments of Ce, Pr, Nd and Sm align parallel with that of Fe, while the magnetic moment of Eu is anti-parallel with that of Fe.
