Abstract
A spin-selective and polarization dependent study at the K absorption pre-edge in hematite -Fe2O3 was performed by means of 1s3p resonant x-ray emission spectroscopy on a single crystal. The experimental results can be modeled using a band structure approach local density approximation LDA U. The spin-selective spectra in connection with the calculations firmly establish metal-oxygen and metal-metal orbital hybridizations. A phase shift in the polarization dependent absorption cross section is observed between the first two absorption features showing directionality in the orbital hybridizationKeywords
