Subject of research: composite magnetic heterogeneous nanostructures, multiferroics, magnetoactive elastomers based on ferromagnetic micro- and nanoparticles, metal films with low coercive force and high magnetic susceptibility. Molecular crystals with magnetic nanoparticles, based on composite structures of magnetic martensitic materials with piezoelectrics and electric treatments.
Theoretical and experimental researches on the built-in mechanical mechanisms and the basic laws of influence of magnetic fields, mechanical stresses on magnetic, optical, electric and transport characteristics of heterogeneous composite meso- and nanostructured magnetic materials are investigated and the basic approaches, methods and received parameters using functional elements based on textured magnetic materials.
A study of meso- and nanostructured magnetic systems with different types of competing interactions. Inhomogeneous multiphase magnets are used as base materials, as well as composite materials consisting of a non-magnetic matrix of various types and magnetic nano- and microparticles introduced into this matrix.
The physical properties of structured magnetoactive elastomers and the magneto-optical properties of molecular systems with magnetic impurities of different types have been studied. These systems have common features characterized by random distribution of phase components and high mobility of parts of magnetic inclusions. Active alternative elastomers have great magnetomechanical effects, which are created by materials with shape memory.
The research and physical mechanisms of hysteresis phenomena, which are observed in experimental studies of magnetic and electrotransport properties of the interface of magnets with strongly correlated electronic states and non-magnetic metal of different types under strong excitation, are established
