Abstract

The electronic structure of La1-xSrxMnO3 has been investigated by photoemission and X-ray absorption spectroscopy. The spectra have been analyzed using a configuration interaction cluster model. Deduced parameters show that the band gap of LaMnO3 is of the p-d gap type while that of SrMnO3 has also considerable p-p character. The shiftof the Fermi level with doping does not follow the simple rigid band picture. The photoemission spectra of SrMnO3doped with electrons show the appearance of “in-gap states” in the band gap of SrMnO3.
