Electronic structure of highly ordered Sr2FeMoO6: XPS and XES studies

We have investigated the electronic structure of Sr2FeMoO6. In order to probe the partial densities of states we applied soft x-ray emission spectroscopy (XES) to the Fe L, the Mo M and the O K edges. We discuss the results in the light of complementary measurements of the valence band by means of x-ray photoelectron spectroscopy (XPS) and first-principles generalized gradient approximation (GGA) and LDA + U band structure calculations [1].
