Golub V. Magnetic structure and properties of artificially produced nano- and heterogeneous materials

The modification of magnetic structure and properties of nano- and heterogeneous materials has been systematically investigated in this work. General relationships and specific peculiarities under the transit molecular and low dimensional magnetics - magnetic nanoparticles - nanoparticle ensembles - magnetic heterogeneous structures have been established. The new model approaches and methods for the analysis of magnetic data to obtain qualitative and quantitative information about magnetic, crystalline and electron structure of such magnetic systems have been developed. The magnetic parameters (such as spin-orbital coupling, zero-field splitting and exchange interaction) for more than fifty new low dimensional magnetics, as well as as well as peculiarities of magnetic structure and properties of nanoparticles of different types ad heterogeneous magnetics have been determined. The correlation between magnetic parameters and composition and crystal structure of materials has also been revealed. It has been shown that It has been shown that taking into account of nonreversible processes of magnetization change under the simultaneous action of acoustic and magnetic waves on magnetoelastic it is possible to explain the formation of special magnetic structure, which is a magnetic image of acoustic signal.
