Department of Theory of Magnetic Phenomena and Magnetic Dynamics of Condensed Matter (No. 01)

Department Chair– D. Sc. Volodymyr Golub

The department includes Laboratory of Magnetic Materials (No. 06).

Department history

The theory of magnetic phenomena and experimental studies of magnetic dynamics have been one of the main research areas of the Institute of Magnetism since its establishment. The Department of Theoretical Physics of the Institute of Metal Physics of the NAS of Ukraine, headed by Academician V. G. Baryakhtar, together with the Department of Film Physics, became the basis for the establishment of the Institute of Magnetism in 1995. From 1996 to 2016, the Department of Theoretical Physics of the Institute of Magnetism was headed by Prof. Yevhen D. Bilokolos.

The development of the experimental base and the expansion of research areas prompted the splitting of the Department of Magnetic Dynamics of Condensed Matter from the Department of Film Physics in 2013. This department was headed by D. Sc. Volodymyr Golub in 2013-2016.

The Department of Theory of Magnetic Phenomena and Magnetic Dynamics of Condensed Media acquired its current form in 2016 by merging the Department of Theory of Magnetic Phenomena and the Department of Magnetic Dynamics of Condensed Matter. Since its establishment, the head of the department has been D. Sc. Volodymyr Golub.

The employees of the department ensure the functioning of the Center for Shared Use of Scientific Equipment "Magnetic and Structural Research".

Research activity

The scientific research of the department is closely related to the activities of scientific schools V. G. Baryakhtar and B. O. Ivanov, whose representatives are a significant part of the department staff.

Currently, the work is carried out in the following main areas:
1. Magnetic dynamics of nanostructures – theoretical and experimental study of the magnetic properties of nanostructured artificial materials with characteristic scales of spin inhomogeneity from submicron to atomic. Significant attention is paid to the study of the physical foundations of creating compact sources of terahertz and subterahertz radiation for use in promising telecommunications and information systems, security systems, space communications, biology and medicine; development of principles for the formation of functional structures with specified microwave and magnetic properties.

2. Thermodynamic and magnetic properties of functional materials with phase transformations – development of the physical foundations of the creation of materials in which the control of structural, mechanical, thermodynamic and magnetic properties can be carried out using a magnetic field, as well as materials with a significant change in magnetic parameters due to the modification of their structural and mechanical properties for use as miniature non-volatile stress sensors in various structures and devices, medical monitoring systems, for the creation of solid-state cooling systems, microactuators, modern communication systems, monitoring systems for infrastructure facilities, etc.3. Development of new mathematical methods for analyzing kinetics, thermodynamics, and nonlinear dynamics of multiparticle systems and nanostructures – study of nonlinear equations that describe real magnetic materials with a complex sublattice structure and taking into account the effects of quantum spin reduction of the sublattice, including states far from equilibrium; kinetic and thermodynamic theory of layered structures; development of the theory of statistical physics and thermodynamics of multiparticle systems.
