Resumen

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.
