Ihor Mychailowytsch Dmytrenko (born July 24, 1928 in Charkow ; † May 17, 2009 ibid) was a Ukrainian - Soviet low-temperature physicist .

Life

Dmytrenko, son of an engineer and a nurse , was evacuated during the German-Soviet War and worked as a locksmith in an aircraft repair shop. In 1946, after finishing school as an external student, he began studying at the Kharkov Polytechnic Institute , which he graduated as a physics engineer in 1952 . He then worked in the development department of the Malyshev plant .

At the end of 1953, Dmytrenko began an apprenticeship in the low-temperature physics department, headed by Academy member BG Lazarev, at the Kharkov Physics and Technology Institute of the Academy of Sciences of the Ukrainian Soviet Socialist Republic (USSR) . In 1958 Dmytrenko successfully defended his candidate dissertation on quantum oscillations of the magnetic susceptibility of metals .

In 1958 BI Werkin , AA Galkin , BN Eselsohn and Dmytrenko formed an initiative group to found the Institute for Low Temperature Physics and Technology (FTINT) of the Academy of Sciences of Ukraine in Kharkov. The Institute was founded in 1960, and Dmytrenko headed the Department of superconductors - Electronics (later Department of superconducting and mesoscopic structures). In 1970 he successfully defended his doctoral thesis on the Josephson effect in weakly bound superconductors. He then became the first deputy of the Scientific Director of FTINT and remained so until 1982. In 1972, on Dmytrenko's initiative, the Faculty of Physics and Technology was founded in the Kharkov Polytechnic Institute , and later the Chair of Technical Low-Temperature Physics. In 1972 Dmytrenko was appointed professor and in 1988 was admitted to the Academy of Sciences of the USSR.

Dmytrenko and his department investigated the behavior of thin-film superconductors in constant and changing electromagnetic fields . In 1965, together with IK Janson and WM Swistunow, he experimentally demonstrated the special electromagnetic effects of superconductor currents through tunnel barriers ( Josephson effect ), which had been theoretically predicted by Brian Josephson . This formed the basis for his doctoral dissertation. Chaotic phenomena were observed in superconducting systems as well as quantum magnetic fluxes in thin cylinders made of common metals, which practically confirmed the Aslamosow- Larkin theory. In the 1990s, macroscopic quantum tunneling and quantum resonance phenomena were observed in systems with Josephson junctions. In 2000 the Dmitrenko collective received the Ukrainian State Prize for superconductivity stimulated by an alternating electromagnetic field and phase changes in thin-film superconductors and high-temperature superconductors. Dmytrenko was invited to a series of lectures by the University of Leiden .

Application-oriented work was also carried out in Dmytrenko's department. These included a wide range of tunable thermometers for superconductor cryogenics and magnetometers . The first magnetocardiograph built in the Soviet Union resulted from this work . In 1967 the first SQUID of the Soviet Union and later the first bolometer was created in Dmytrenko's department .
