Resumen:
We have measured Mn-2p photoemission spectra in Mn perovskites doped by two methods: La12xCaxMnO3 and LaMnO3þd.Intra- and inter-series comparisons reveal that the position and intensity of the Mn-2p satellite depend only on the level ofdoping, and that it can always be decomposed into the satellites of the end members LaMnO3 and CaMnO3. We have fitted thespectra of the end members with the configuration–interaction cluster model and show that the linear combinations of thesecalculated spectra reproduce correctly all the details of the spectra of the doped compounds. q 2002 Elsevier Science Ltd.
