抄録

The electronic structure of La_1-xSr_xMnO₃ 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.
