CAMPUS è l'Archivio istituzionale delle pubblicazioni scientifiche dell’Università di Camerino. E’ un sistema aperto, pubblico e interoperabile che raccoglie, conserva ed espone i dati relativi alle attività e ai prodotti della ricerca dell’Ateneo con lo scopo di migliorarne la visibilità e di favorirne l’impatto a livello nazionale e internazionale.

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 hybridization.

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 hybridization.
