“…Comparing earlier [2,3] and the present studies of the valence band of La 1±x Sr x MnO 3 one can say that the peak lying in the higher-binding part of the spectrum does not change ist position as the Sr fraction increases. The second peak moves towards the Fermi level by about 1 eV when changing x between 0.3 and 0.4.…”

“…The sample with nominal composition La 0.6 Sr 0.4 MnO 3 has been prepared by the standard method [2]. La 0.6 Sr 0.4 MnO 3 is ferromagnetically metallic below the Curie temperature (T C = 350 K).The XPS spectrum was obtained for radiation with photon energy of 1.4866 keV, AlK a source (for details see [2]). The photoemission spectrum in the valence band region at room temperature is shown in Fig.1.…”

“…The calculations of the density of states (DOS) were performed based on the tightbinding linear muffin-tin method (TB LMTO) [4] (technical details of the calculations are the same like those described in Ref. [2]). The XPS spectra were calculated from the partial DOS weighted with atomic photoemission cross-sections [5] for the photon energy used in the experiment.…”

Core photoemission spectra of oxygen atoms in perovskite manganites La 1−x A x MnO 3 (A=Sr, Pb)

The electronic structure of the colossal magnetorcsistance perovskite manganite materials, Lao.65Pbo.35MnO3 and Lao.TSro.aMnOa, has been studied by X-ray photoemission spectroscopy (XPS). The ls core level spectra of oxygen (O(Is)) exhibit double-peak structure with asymmetric intensities characteristic for different clmmieal environments. Ab-initio calculations allow identifying source of the peaks. The higher peak in the lower binding energy is associated with ten of oxygen atoms, and the rest of oxygen atoms (two) give the weaker peak in the higher binding energy part of the XPS spectra. The weaker peak is associated only with these two oxygen atoms which are located in the lanthanum atoms plane without Sr or Pb impurities. PACS: 71.20 Dg; 79.60.-i; 75.30 Et
