Fe and Mo valences in Sr<inf>2</inf>FeMoO<inf>6</inf>

Abstract:

The valences of Fe and Mo in Sr2FeMoO6 are investigated by means of X-ray absorption and photoemission spectroscopies. We find that the d occupations are similar to those of Fe in Fe2O3 and Mo in MoO3. Considering the covalency, however, we argue that the ground state is closer to a Fe+3(3d5)-Mo+5(4d1) configuration than to a Fe+2(3d6)-Mo+6(4d0) configuration. © 2001 Published by Elsevier Science Ltd.
