Essay

The thesis deals with the finding the regularities of the influence of electronic structure parameters and peculiarities of electronic correlations on the temperature and compositional ranges of phases’ stability in metallic systems with chemical and topological disordering. The physical principles of the formation of magnetic characteristics have been considered for these systems. The influence of composition, structural state and preparation conditions on magnetic state of the constituent atoms has been investigated for antiferromagnetic chromium-based alloys, amorphous, nanocrys-talline systems and composite materials containing 3d-element. Besides, the role of the exchange correlations and electronic struc-ture parameters (namely, density-of-electronic-state spectra) in the specification of the temperature and compositional ranges of phases’ stability in the listed systems has been evaluated. Two types of atomic clusters have been proved to exist in the alloys under study. The principal characteristics of these clusters have been ascertained.
