He was physicist-researcher, Doctor of Sciences (Physics and Mathematics), professor, Corresponding Member of the Academy of Sciences of the Ukrainian SSR, the State Prize of the Ukrainian SSR in Science and Technology, director of the Institute for Low Temperature Physics and Engineering (1988–1991).[2][3]

Education and training edit

Anatolii Illarionovich Zvyagin studied at the Radiophysics Department of the Kharkov State University (Diploma in 1959).  After the studies at the University he worked as an engineer at one of the enterprises of the cosmic branch; he took part in the preparation to flights of the first spaceships. In 1961 he had started post-graduate studies at the Institute for Low Temperature Physics and Engineering of the Academy of Sciences of the Ukrainian SSR. Five years later, he obtained the Candidate of Science (PhD) degree; thesis "Features of the infrared spectra of antiferromagnetic Co compounds" (scientific advisers: B.I. Verkin, the founder and the first director of the ILTPE, and V.V. Eremenko). From 1966 on, A.I. Zvyagin was the head of the department of the radio-spectroscopy of semiconductors and insulators (later the department of infrared and radio-spectroscopy of magnetic insulators).[4][5]

In 1974 he has obtained the Doctor of Science (Physics and Mathematics) degree, thesis "Features of the energy spectrum and phase transitions in magnets with the low symmetry of crystal lattice". Since 1976 he was the Deputy Head in Research of the ILTPE. In 1978 he became the professor of Physics. In 1985 he has been elected as the Corresponding Member of the Academy of Sciences of the Ukrainian SSR (Experimental Solid State Physics). In 1991 he has obtained the State Prize of Ukraine in Science and Technology (for the detection and investigations of the new type of resonances, structures and magneto-elastic anomalies in low-dimensional antiferromagnets).[6] A.I. Zvyagin is the author and co-author of more than 150 scientific publications. He was the supervisor of 15  Candidate of Science  (PhD) theses. Five of his former students became Doctors of Sciences. He was the member of the Editorial Board of the scientific journal "Fizika Nizkikh Temperatur" (published by the AIP as "Low Temperature Physics"). He conducted pedagogical activity, teaching many courses of lectures at the Kharkov State University and Kharkiv Polytechnic Institute.  From 1988 till 4 May 1991 (died from the heart attack) he was the director of the Institute for Low Temperature Physics and Engineering of the Academy of Sciences of Ukrainian SSR.[4][5]

Scientific Activity edit

The scientific activity of A.I. Zvyagin was devoted to experimental studies of low-symmetric and low-dimensional magnetic insulators at low temperatures. Among the main achievements of A.I. Zvyagin and his co-workers one can mention the discovery of the new phases and Phase Transformations in systems of rare-earth tungstates and molybdates. His works, devoted to the investigations of the low-frequency branches of spectra of highly anisotropic magnets and layered ferroelectric elastics, are widely known. Principally important results were obtained by A.I. Zvyagin when studying low temperature structural and magnetic phase transitions in crystals with the strong spin-phonon interaction. In the framework of the pioneer studies of the dynamical resonance properties of low dimensional (one- and two-dimensional) magnets principally new exchange modes of oscillations of such magnetic systems were discovered experimentally. Also, important results were obtained by A.I. Zvyagin and co-workers in studies of magnetic properties of undoped cuprates, which manifest the high-temperature superconductivity at the optimal doping.[4][5]
