Abstract

In order to investigate the change in the electronic structure with Mn doping of SrRu1-x Mnx O3 (SRMO), we have performed soft x-ray synchrotron photoemission spectroscopy (PES) and x-ray absorption spectroscopy (XAS). In the soft x-ray PES spectra, the sharp peak structure near the Fermi level (EF), which was clearly observed in SrRuO3, was suppressed accompanied with Mn doping in SRMO. In the Mn2p XAS and Mn2p-3d resonant PES spectra, we have confirmed the existence of Mn3+ ions with the electron doping to Mn3d eg states and Mn3d partial density of state never have finite intensity at EF in SRMO. These results suggest that the metal-insulator transition of SRMO with Mn doping is originated from the charge transfer from the itinerant Ru4d t 2g bands to the localized Mn3d eg orbitals.
