Dmitri Dmitrievich Mishin

Dmitri Dmitrijewitsch Mishin ( Russian Дмитрий Дмитриевич Мишин ; born January 25 / February 7, 1919 in Turinsk ; † August 26, 1998 in Tver ) - was a Soviet and Russian physicist, qualified doctor of physics and mathematics, professor and founder of the scientific school for Magnetic Science at Tver State University .

Studies and career entry

In 1934 he started working in the Irbit City Inventory Office . From 1936 to 1938 he studied at the workers' faculty of the Perm Agricultural Institute in Irbit. During his studies at the Faculty of Physics and Mathematics of the Ural State University (1938-1942) one of his mentors was RI Janus. After graduating from the university, in 1942 he worked as a spectroscopy engineer in the military plant No. 217 Geophysics of the Ministry of Armaments (currently Yalamow Optical-Mechanical Factory of the Urals), which was evacuated from Moscow in 1941. The laboratory was headed by a graduate of the Department of Magnetism, Faculty of Physics, Moscow State University AA Chobanyan. Dmitri Mishin later headed the technology department at the same plant until 1948.

Work at the Ural State University

In 1951, after completing his doctorate, he defended his dissertation on the topic of the effect of low elastic stresses on the initial susceptibility of ferromagnets to failure . 1950–1971 he worked as a lecturer, then as a junior professor in the Department of Experimental Physics, then from 1958 in the Department of Magnetism, Faculty of Physics at the Ural State University. The subject of the studies was the effect of a real, faulty crystal structure on the magnetic properties of magnetic materials, including those with rare earth components. The phenomenological quantitative laws of the effect of dislocations on the domain structure and the magnetic properties of electrical steels have been established. In the years 1954–1955, Professor JS Shur and lecturer DD Mishin and doctoral students investigated the homogeneity of the magnetic properties of transformer steel along a sheet metal on behalf of the Verkh-Isetsk-Metallwerk. DD Mishin was one of the founders and directors (1962–1971) of the Problem Laboratory for Permanent Magnets (PLPM) at the Ural State University (currently Department for Solid State Magnetism of the Research Institute for Physics and Applied Mathematics). In 1969, the joint research work of the PLPM with the Pyshma test facility led to the organization of a test site for the production of permanent magnets based on earth metal-cobalt alloys. The first magnets were made only by pressing the original powder, later a special powder sintering technology was developed and applied that made it possible to improve the magnetic and operational properties of permanent magnets. In 1970 DD Mischin defended his dissertation (habilitation) on the subject of the effect of the dislocation structure on the susceptibility and coercive force of silicon-containing iron .

Work at Tver State University

In 1971 the Pedagogical Institute in the city of Kalinin (until 1931 and since 1990 Tver ) was elevated to university level. Dmitri Mishin moved to Kalinin and started working at Kalinin State University (KSU). In 1972 he organized the department for magnetism at the Faculty of Physics at KSU. In his doctoral theses, his doctoral students examined the magnetic reversal processes in rare earth metal alloys (Sm, Pr, Nd, Dy, etc.) with metals of the iron and boron groups. A method of manufacturing permanent magnets with improved properties has been developed, establishing the laws governing changes in the domain structure of permanent magnets. The implementation of the results of his work in industry was recognized with gold and silver medals at the Soviet Exhibition of Achievements in National Economy in 1987–1990. In 1988 the 18th All-Union Conference on the Physics of Magnetic Phenomena at the Institute for Magnetism of the KSU took place in Kalinin on the decision of the Academy of Sciences of the USSR. In 1996 DD Mischin became an honorary professor at Tver State University.

Scientific and educational activities

DD Mischin is the author of around two hundred scientific publications, a monograph and fifteen invention certificates, two invention patents, two utility models and the sole inventor and patent holder of two inventions with the patent numbers 2125333 and 2112294.

memory

In May 2002, at the All-Russian School Seminar Magnetic Anisotropy and Hysteresis Properties of Rare Earth Alloys , which was dedicated to the 30th anniversary of the Institute of Magnetism at Tver State University , Rector AN Kudinov proposed the establishment of a scholarship named after DD Mishin for the best students of the Faculty of Physics.
