Abstract

We have investigated the magnetic structure of a Sr₂FeMoO₆ single crystal by X-ray magnetic circular dichroism at the L_2,3 edges of Fe and Mo sites. The spin magnetic moments we find on Fe (3.05 μ_B) and Mo (-0.32 μ_B) give, for the first time, a direct confirmation of their ferrimagnetic ordering. The presence of a finite spin moment on Mo together with only very small orbital moments on both Fe and Mo confirms that the predicted half-metallicity of the Sr₂FeMoO₆ compound is due to a configuration with five localized d electrons forming a high-spin moment on Fe and one s antiparallel delocalized electron shared between the Mo and the other sites.
