Opis:: We present the results of the electronic band structure study of Ge$\text{}_{0.9}$Mn$\text{}_{0.1}$Te epilayers, clean and modified in situ by deposition of manganese atoms. The sets of resonant photoemission spectra were measured for the photon energy range covering the energy of Mn 3p→3d transition (45

Opis:: The high-energy X-ray photoelectron spectroscopy was used to determine the composition and chemical structure of epitaxial LaNiO$\text{}_{3-x}$ films obtained by a reactive dc magnetron sputtering. It was found that the oxide and hydroxide species of La and Ni are on the films surface. The thickness of hydroxide enriched layer, estimated from the oxide and hydroxide peak intensities, is about 2 nm.

Opis:: Resonant photoemission spectroscopy, with application of synchrotron radiation, was used to study the valence band electronic structure of clean surface of (EuGd)Te layers. Fano-type resonant photoemission spectra corresponding to the Eu 4d-4f transition were measured to determine the contribution of 4f electrons of Eu$\text{}^{2+}$ and Eu$\text{}^{3+}$ ions to the valence band. The resonant and antiresonant photon energies of Eu$\text{}^{2+}$ ions were found as equal to 141 V and 132 eV, respectively and for Eu$\text{}^{3+}$ ions were found as equal to 146 eV and 132 eV, respectively. Contribution of Eu$\text{}^{2+}$4f electrons was found at the valence band edge while for Eu$\text{}^{3+}$ it was located in the region between 3.5 eV and 8.5 eV below the valence band edge.

Opis:: We report valence states of ions in $La_{0.7}Ce_{0.3}MnO_3$ thin films grown by a reactive dc magnetron sputtering. The measurements were performed by means of high-energy X-ray photoelectron spectroscopy using synchrotron radiation. It was found that Ce ion in the compound is either in tetravalent or trivalent chemical state, manganese is in divalent, trivalent and tetravalent states, while La ion existing in oxide and hydroxide chemical species is in trivalent state.
