We present a line-shape analysis based on atomic single configuration Mn3 d6 multiplet calculations of core-level and valence-band spectroscopy data from metallic ferromagnetic Mn5 Ge3. We show that atomic calculations can fit most of the spectral features measured in Mn2p-3d x-ray absorption and circular dichroism, in Mn2p and Mn3s 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 Mn5 Ge3 system.

Abstract
We present a line-shape analysis based on atomic single configuration Mn3 d6 multiplet calculations of core-level and valence-band spectroscopy data from metallic ferromagnetic Mn5 Ge3. We show that atomic calculations can fit most of the spectral features measured in Mn2p-3d x-ray absorption and circular dichroism, in Mn2p and Mn3s 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 Mn5 Ge3 system.
