Opis:: We study CdTe:Cr single crystals grown by the physical vapor transport method from pre-synthesized (Cd,Cr)Te alloys with 5 at.% of chromium nominal content. Macrodefects in the form of (111)-oriented thin platelets of dopant-related second phases were detected by scanning electron microscopy patterning of the chemically treated surfaces of the crystals. Magnetic properties of the crystals were investigated by ferromagnetic resonance using X-band Bruker spectrometer (9.43 GHz). Their ferromagnetic resonance spectra show several broad lines, which position depends on the orientation of the sample in relation to the external magnetic field in spectrometer. The angular dependences of ferromagnetic resonance spectra are interpreted in the frame of shape anisotropy of ferromagnetic resonance of the planar defects embedded in a weak magnetic CdTe matrix.

Opis:: Optical properties of ZnO films doped by Al in the range 0.5 to 7 at.% and deposited by atomic layer deposition were studied in visible and infrared spectral range. Spectral dependences of film optical permittivity were modeled with the Lorentz-Drude approximation resulting in ZnO:Al plasma frequency and plasma damping parameters. We observed changing electron effective mass from 0.29m₀ to 0.5m₀ with increasing electron concentration in the range (0.9-4) × 10²⁰ due to the phenomenon of conduction band non-parabolicity. Comparing the results of optical and electrical investigations we can see that the main scattering mechanism is the scattering on grain boundaries (its contribution is about 60%).
