Electron structure and valence state of CeM2P2 (Fe, Co, Ni) compounds

Abstract X-ray photoelectron, emission and absorption spectroscopy have been used to study the electron structure and valence state of new ternary intermetallic compounds, which crystallize in the CeGa 2 Al 2 structure. X-ray emission spectra of M and P elements in CeM 2 P 2 compounds have been investigated and the density of the total and partial electron states in this phase has been calculated within the self-consistent LMTO method. Effective filling numbers of electrons in different bands of components in CeM 2 P 2 compounds have been calculated. X-ray spectra of M and P elements in ternary CeM 2 P 2 (M=Fe, Co, Ni) compounds were obtained at 300 K using a tube spectrometer equipped with an RKD-01 co-ordinate detector.
