Abstract

We have measured the site-specific valence-electronic structure of α-Fe2O3 by using a spatially modulated X-ray standing wave as the excitation source for photoemission. Contributions to the valence band density of states from oxygen and iron ions are separated by this method. Both a bonding and nonbonding state originating from the oxygen ions are obtained. The valence densities of states from iron agree well with predictions based on configuration interaction cluster calculations by Fujimori et al., which considered charge transfer from ligand to metal. The effects of strong hybridization between Fe and O valence states to X-ray emission and resonance photoemission are also evident.
