Atomic approach to core-level spectroscopy of delocalized systems: Case of ferromagnetic metallic Mn5Ge3

We present a line-shape analysis based on atomic single configuration Mn 3d6 multiplet calculations of core-level and valence-band spectroscopy data from metallic ferromagnetic Mn5Ge3. We show that atomic calculations can fit most of the spectral features measured in Mn 2p-3d x-ray absorption and circular dichroism, in Mn 2p and Mn 3s core-level photoemission, as well as for the delocalized electrons in valence-band photoemission. This indicates that, in spite of the metallic nature of the compound, atomic effects can play a relevant role to determine the physical properties of the Mn5Ge3 system.
