Abstract

Neutron diffraction and magnetic susceptibility has been used to study the crystalline and magnetic structures of Sr2FeMoO6. The compound crystallizes into a tetragonal I4/m symmetry. Both of the Fe and Mo moments were found to be ordered at low temperatures, with the ordered moments beginning to develop below 450 and 165 K for the Fe and Mo ions, respectively. The spin configuration may be viewed as consisting of ferromagnetic Fe/Mo planes that are mutually intersected at an angle of 120°, and form a non-collinear structure. The saturated moments for the Fe and Mo ions were 〈μZ〉=3.30(4)μB and 1.74(9)μB, respectively.
