In 1966 graduated from the Physics Department of Kharkov State University, Gorky, in 1974. - Post-graduate department of general physics with specialization in "physics of magnetic phenomena." In 1977 defended her Ph.D. thesis: "Investigation of exchange interactions in iron by diamagnetic mnogopodreshotochnyh substitutions."
Since 1967 worked at the Kharkov State University, Department of General Physics in the following positions: junior and senior research fellow of SRD, since 1974. - An assistant and then associate professor. HES is a member of the Physics Department.
The direction of scientific activity - frustrated magnetic systems and spin glasses. On this subject under the authority reserved two theses: 1.Tkachenko MV "Disordered spin-glass state in diluted ferrimagnetic oxides, Kharkov, 1990. 2. Ghalib Mohammad "Magnetic and thermal properties
Heisenberg spin-glass systems, Kharkov, 1994., has over 60 scientific publications.
Teaching the courses: "General Physics" for students of Chemical Faculty of the University, "Recent developments in the physics of magnetic phenomena" - a common course for graduate physics department, as well as three elective courses for students of the specialization of General Physics: 1.Magnitnye properties of atoms and weak magnetism, 2. The physics of magnetic phenomena in the condensed state 3. The properties of magnetically ordered materials
