Opis:: The resonant photoemission spectroscopy was applied to investigate the valence band electronic structure of semimagnetic semiconductor Pb$\text{}_{0.92}$Mn$\text{}_{0.08}$Se crystal and to determine the contribution of Mn 3d electrons to the valence band. The set of energy distribution curves and constant initial states spectra were taken for by energies in the region (40-60 eV) close to the Mn 3p-3d transition. The electrons Mn 3d hybridize and contribute to the valence band electrons of the crystal and main density of states contribution appears in the energy 3.5 ± 0.2 eV below the valence band edge.

Opis:: The synchrotron radiation in the energy range between 40 and 80 eV was applied to investigate the electronic structure of Hg$\text{}_{0.7}$Mn$\text{}_{0.3}$Se, Hg$\text{}_{0.88}$Fe$\text{}_{0.12}$Se and Hg$\text{}_{0.93}$Co$\text{}_{0.07}$Se crystals by means of the resonant photoemission spectroscopy. The set of energy distribution curves was measured in the region near the M (M = Mn 3d$\text{}^{5}$, Fe 3d$\text{}^{6}$, Co 3d$\text{}^{7}$) 3p-3d transitions. In order to determine thoroughly the Fano type resonance energy the constant initial states curves were measured.

Opis:: We report the results of a resonant photoemission study of Zn$\text{}_{1-x}$Co$\text{}_{x}$S. A Co 3d derived contribution to the valence band spectra was revealed as a 5 eV wide structure with two maxima: at the edge of the valence band and about 4 eV below the edge. The results were compared with the total DOS distribution resulting from tight binding-coherent potential approximation calculations.

Opis:: The synchrotron radiation was applied to measure resonant photoemission spectra (Fano-type Gd 4d-4f resonance), constant initial states and constant final states to study the valence band electronic structure of Sn$\text{}_{0.96}$Gd$\text{}_{0.04}$Te crystal. The resonant energy was found equal to 150.3 eV. The electrons 4f were found to contribute to the valence band of the crystal with the maximum located at 9.5 eV below the valence band edge whereas 5d electrons contribute at the crystal valence band edge.
