Mn-2p XPS spectra of differently hole-doped Mn perovskites

We have measured Mn-2p photoemission spectra in Mn perovskites doped by two methods: La1−xCaxMnO3 and LaMnO3+δ. Intra- and inter-series comparisons reveal that the position and intensity of the Mn-2p satellite depend only on the level of doping, and that it can always be decomposed into the satellites of the end members LaMnO3 and CaMnO3. We have fitted the spectra of the end members with the configuration–interaction cluster model and show that the linear combinations of these calculated spectra reproduce correctly all the details of the spectra of the doped compounds.
