Opis:: In the paper there are shown the changes in optical properties of $TiO_2$ thin films prepared by dc magnetron sputtering at different gas flow rates. We found that there is a drastic change in optical properties such as optical transmission, refractive index, extinction coefficient and optical band gap with the gaseous flow rate and composition. We observed an improvement in optical properties of the films that had been deposited at higher gaseous flow rate and at a certain gaseous composition.

Opis:: In this paper we report our experimental and theoretical studies on the effect of Gd impurity on the physical properties of the Heusler half-metallic ferromagnet $Co_2MnSi$. The analysis of the band structures of the doped alloy shows that the half-metallic properties are completely conserved if Gd substitutes Mn atoms. This effect is not determined by the spin-orbit interaction, but through the coupling between the R(4f) spin with the Mn(3d) itinerant electron spins. We evaluate the strength of such a coupling by calculating, in an ab initio fashion, the total energy of $Co_{16}GdMn_7Si_8$ compound for a parallel and antiparallel f-d coupling. The obtained magnetic moments of Co or Mn sites are in good agreement with the experimental ones.
