Opis:: Photoreflectance spectra were measured at room temperature for energies in the vicinity of the E$\text{}_{0}$ critical point for p-type as well as n-type doped GaAs/SI-GaAs structures. Depending on the doping concentration the existence of two photoreflectance subsignals was observed; the first one arises from the surface space charge region while the second one from the interface region. The decomposition of photoreflectance spectrum into surface and interface subsignals was based on the photoreflectance measurements carried out for different wavelengths of the laser pump beam.

Opis:: The electronic structure, pressure and temperature dependence of thermodynamic properties of RNi₅Sn (R = La, Ce, Pr, Nd) compounds are calculated by ab initio full potential local orbital minimum-base(ver. 9 and ver. 14) method. These compounds crystallize in the hexagonal crystal structure (space group $P6_{c}$/mmc, No. 194). The band calculations were performed in the scalar-relativistic mode for the exchange correlation potentials in the form of the Perdew-Burke-Ernzerhof general gradient approximation. In this work we present the band structures of LaNi₅Sn, CeNi₅Sn, NdNi₅Sn and PrNi₅Sn compounds. The thermodynamic properties (bulk modulus, Debye temperature) are calculated in the Debye-Grüneisen model using the equation of states in the form of Birch-Murnaghan, Poirier-Tarantola and Vinet. Our results have shown that values of thermodynamic properties depend on the method of calculations.

Opis:: This paper reviews recent progress in the studies of magnetic dilutions on magnetic properties of two frustrated systems: magnetoplumbite-like $SrGa_{12-x}Cr_xO_{19}$ and kagome staircase $Co_3V_2O_8$ doped with Mg ions. In the first group of compounds magnetic properties are determined by magnetic defects arising due to doping. In the case of kagome staircase compounds magnetic dilution suppresses effects of crystal field acting on magnetic ions. In particular, the dilution decreases magnetocrystalline anisotropy and anisotropy of magnetization.

Opis:: The band structures and the magnetic properties of $Co_{3}V_{2}O_{8}$ compound have been calculated by ab initio scalar-relativistic full potential local orbital method within the local spin density approximation. The band calculations were performed for para-, ferro-, and antiferromagnetic $Co_{3}V_{2}O_{8}$ compounds. The main contribution to the density of states at the Fermi energy comes from minority 3d states of cobalt atoms.
