Opis:: Surface photovoltage spectroscopy (SPS) measurements for Cd$\text{}_{1-x}$Mn$\text{}_{x}$Se single crystals between 80 and 300 K at the pressure of 10$\text{}^{-4}$ Pa were performed. The Fermi level energy was calculated. From the SPS curves the energy values connected with the electron transitions have been determined. Four types of effects have been stated: energy gap, shallow states close to the conduction band and two energy states connected with the structural defects, the native ones and those related to introduction of manganese into the CdSe matrix.

Opis:: The surface electronic structure of the Cd$\text{}_{1-x}$Fe$\text{}_{x}$Se and Cd$\text{}_{1-x}$Fe$\text{}_{x}$Τe crystals with x = 0 and x = 0.03 has been studied by Surface Photovoltage Spectroscopy (SPS). The change of surface photovoltage was observed due to photo-excitation of the electrons from the deep donor state Fe 3d to conduction band edge. This gave possibility to determine energy position of the Fe 3d state at 0.64 and 0.15 eV over the top of the valence band for CdSe and CdTe, respectively.

Opis:: Surface photovoltage measurements performed for the Cd$\text{}_{0.85}$Mn$\text{}_{0.15}$Te single crystal samples intrinsic and gallium doped have shown influence of gallium doping on height and sign of the surface voltage barrier. From results of the surface photovoltage spectroscopy (SPS) measurements thevalues of acceptor, donor and manganese states energies have been determined. The photoconductivity (PC) measurements confirmed the effects found on the SPS curves.

Opis:: Boron was partially substituted by phosphorus (3 at.%) in two Si-poor Fe-Nb-Cu-B-Si Finemets. Mostly non-significant changes were observed after vacuum annealing at 500°C, whereas equivalent Ar annealing resulted in significantly better soft-magnetic properties, which suffer from compressive surfaces stress. Possibly by hampering surface crystallization, the substitution eased the surfaces stress and reduced undesired off-axis anisotrophy at the cost of limiting the useful annealing temperature.

Opis:: Post processing limits for iron-rich Fe-Cu-Si-B-P high-induction rapidly-quenched ribbons have been tested. 530°C/20 min is already too much, formed borides being the essential culprit of magnetic properties deterioration. Unlike standard Si-poor Fe-Nb-Cu-B-Si Finemets, these alloys annealed even in "technical" Ar below the upper limit do not create significant squeezing surfaces.

Opis:: Co-Fe-Mo-Mn-Si-B metallic glass ribbon (Vitrovac 6030) was subjected to the isothermal annealing at temperatures in the range 523-873 K so as to produce a series of samples with gradually coarser microstructure. For this series of samples a giant increase in the coercivity, exceeding three orders of magnitude, is observed. This increase is interpreted in terms of the strengthening of the pinning effect of the nanocrystalline structure on the moving domain walls. It is shown that the anisotropy of the created crystallites is mainly responsible for the increase in the pinning force since the effective anisotropy seen by the wall becomes larger and larger with the gradual increase in the density and size of the grown particles.
