Abstract: Constant increase of magnetic recording density requires application of modern ferromagnetic materials with high value of magnetic anisotropy constant and coercivity. Thin films on the bases of L1₀-FePt ordered phase is one of such materials. However, practical application of such materials requires to solve a number of materials science problems such as decrease of ordered phase formation temperature, formation of its predominantly oriented grains and increase of coercivity. Factors that affect structure formation and properties of FePt based films have been examined in this study. A number of modern studies aimed on solving problems mentioned above have been analyzed.

Abstract: By the methods of Auger-spectroscopy and mass-spectrometry of secondary ions, small-angle electron diffraction, X-ray and resistometry analyses the solid-state reactions in the Ti(5 nm)/ Ni(24 nm)/Si₍₀₀₁₎ thin film system at annealing in running nitrogen in the temperature interval of 723 – 1273 К are investigated. Regularities of phase transformations, consistency of solid-state reactions, layer-by-layer redistribution of components during annealing, features of surface morphology during formation of inclusions of silicide phases are established.

Abstract: The Problem of Solving Diffusion Equation with Free Boundary which Appeared during the Modeling of the Spherical Inclusion Formation Process within Spherical Domain Is Examined. the Algorithm and the Software Were Developed on the Basis of the Rothe Method in Combination with the Integral-Equations Method for their Numerically-Analytical Solution. Results of the Calculations Are Illustrated Graphically.
