Dmitrenko, Igor Mikhailovich

Igor Dmitrenko was born in Kharkov in 1928 in the family of an engineer and an operating sister. During World War II, he was evacuated and worked as a mechanic in aircraft repair shops ^[3] , in 1946, having graduated from school as an external student, he entered the Kharkov Polytechnic Institute , where he graduated with a degree in physics engineer in 1952 ^[4] . After graduation, he worked at the plant named after Malysheva is a research engineer in the experimental department.

At the end of 1953 he entered the postgraduate study at the UFTI in the Department of Low Temperature Physics, headed by Academician B.G. Lazarev , where he worked until May 1960. In 1958 he defended his thesis on quantum oscillations of the magnetic susceptibility of metals.

In 1959, Dmitrenko joined the initiative group to create the Physicotechnical Institute of Low Temperatures of the Academy of Sciences of the Ukrainian SSR (FTINT). The following year, he headed the department of superconducting electronics (later renamed the department of superconducting and mesoscopic structures) at the newly created institute. In 1970 he defended his doctoral dissertation on the results of studies of the Josephson effect in loosely coupled superconductors. From this year to 1982, he worked as the First Deputy Director of FTINT for scientific work. On the initiative of Dmitrenko, in 1972 the Physics and Technology Department was established at the KhPI, and later the Department of Technical Cryophysics.

Since 1972 - professor . Since January 1988 - academician of the Academy of Sciences of the Ukrainian SSR ^[5] . In the last years of his life, he worked as the chief scientific associate of the FTINT superconducting and mesoscopic structures department. He died on May 17, 2009 .

The department of FTINT, headed by Dmitrenko, was studying the behavior of thin-film superconductors in constant and variable electromagnetic fields . In 1965, together with I.K. Yanson and V.M. Svistunov, Dmitrenko received experimental confirmation of electromagnetic radiation in tunnel structures, theoretically predicted by Brian Josephson ^[6] . Subsequently, these observations formed the basis of his doctoral dissertation.

The Dmitrenko group observed chaotic phenomena in superconducting systems and quantization of the magnetic flux in thin cylinders of ordinary metals, in practice confirmed the Aslamazov - Larkin theory on the nonlinear dynamics of quantized vortices in a dynamic mixed state, and stood at the origins of the concept (it was later confirmed experimentally) of the phase slip of the superconducting parameter in wide superconducting films as a general resistance mechanism during the destruction of superconductivity by electric current . In the 90s of the twentieth century, Dmitrenko and his colleagues made observations of macroscopic quantum tunneling and quantum resonance phenomena in the systems of so-called Josephson contacts. In 2000, a team led by Professor Dmitrenko was awarded the State Prize of Ukraine for a series of works “Superconductivity stimulated by an alternating electromagnetic field and phase slipping processes in thin films of superconductors, including high-temperature ones” ^[2] . Dmitrenko was invited with a course of lectures to the Leiden Laboratory ( Netherlands ) ^[3] .

In the laboratory of Dmitrenko, applied developments were also carried out. It created wide-range superconducting cryogenic thermometers, as well as quantum magnetometers and high-sensitivity gradiometers. Based on these developments, the first magnetocardiograph in the USSR was subsequently created in . In 1967, the first SQUID in the Soviet Union was created in the Dmitrenko department, and later the first bolometers in the country ^[3] .
