Opis:: In the article the results of the research aimed at the recognition of the correlation between the Ni-Fe film thickness and its magnetic domain structures are described. Magnetic thin films were prepared by pulse magnetron sputtering. Obtained thin film thicknesses were in the range of 47.6-326.0 nm. Magnetic domain structures were imaged using magnetic force microscopy. In order to obtain quantitative description of magnetic domains images, the algorithms designed for topography parameters determination were applied, enabling the comparison of specific factors related to the magnetic properties of the samples. Utilized approach provided the analysis of the impact of sputtering parameters on the morphological and magnetic properties of obtained films.

Opis:: The diffusive maxima of phonon signals are studied for a number of solid solutions of rare earth atoms in yttrium aluminum garnets. The used exact formula for the diffusion constants allows for qualitative discussion of the obtained results. The established energy of phonons, forming the diffusive maximum of phonon signal of the temperature T$\text{}_{H}$ arriving at the bolometer, ranges from 3.2k$\text{}_{B}$T$\text{}_{H}$ to 4.2k$\text{}_{B}$T$\text{}_{H}$, which is in reasonable agreement with the existing estimations. The qualitative analysis allows us to estimate the contribution, made by the rare earth ions occupying the octahedral positions of the sixfold oxygen coordination, to the scattering of phonons due to lattice imperfections in yttrium aluminum garnets.

Opis:: Paramagnetic centers in melanin existing in pigmented soil fungi Cladosporium cladosporioides cultured at acidic (4, 5, 6), neutral (7), and alkaline (8) pH were studied by EPR method. o-semiquinone free radicals (g: 2.0032-2.0040) concentration in melanin biopolymer increased for pH from 4 to 6, decreased at pH 7, and reached the maximum value at pH 8. It may be expected that melanin free radicals reactions with small molecules (metal ions, drugs) are the most effective at pH between 6 and 8. Slow spin-lattice relaxation processes exist in the all studied melanin samples.
