The influence of doping on the magnetic and structural properties of the double perovskite Sr2FeMoO6

Abstract The half-metallic compound Sr2FeMoO6 has been doped with 25% Cr, Mn or Co on the Fe, Mo sites. High-resolution neutron diffraction was used to determine the cation site occupation, the magnetic structure at 2 K and the tetragonal distortion accompanying the magnetic state. The valence state of the different cations is discussed using the measured interatomic distances.
