ABSTRACT
The valence band electronic structure of a compound with the HfFe2S2 crystal lattice type has been established for the first time based on X-ray emission spectroscopy measurements. Band structure and theoretical spectra of X-ray emission bands of atoms located in non-equivalent crystallographic positions are calculated by means of the LMTO method in non-relativistic approximation. A satisfactory agreement between theoretical and experimental data is achieved.57Fe Mossbauer absorption measurements confirm iron atoms occupying non-equivalent positions in the crystal lattice.
