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:: Resonant photoemission experiments were carried out in order to reveal the contributions of partly filled Eu 4f$\text{}^{7}$ and Gd 4f$\text{}^{7}$ shells to the valence bands of Pb$\text{}_{0.95}$Eu$\text{}_{0.05}$S and Pb$\text{}_{0.95}$Gd$\text{}_{0.05}$S crystals. The coupling between these orbitals and the host electronic states is discussed.

Opis:: Resonant photoemission experiments were performed in order to reveal the contributions of half-filled Gd 4f$\text{}^{7}$ shell to the electronic structures of Sn$\text{}_{0.95}$Gd$\text{}_{0.05}$Te and Pb$\text{}_{0.95}$Gd$\text{}_{0.05}$S crystals. The influences of the Gd 4f$\text{}^{6}$ final-state multiplet splitting and f-ligand hybridization on the shapes of the spectra are discussed.

Opis:: Photoemission measurements using synchrotron radiation were performed on PbYbTe (bulk crystal) and CdYbTe (MBE thin film). The resonant enhancement of the photoemission was applied for investigation of the contribution of Yb 4f electrons to the valence band. The set of the energy distribution curves was collected for energies in the region close to the 4d-4f Fano transition. The Yb 4f$\text{}^{14}$ were observed at the binding energies close to the edge of the valence band while the 4f$\text{}^{13}$ states were revealed deep in the valence band.
