Nikolai Sergeevich Akulov (12.12.1900, Orel, Russia - 21.09.1976), physicist. Academician of the National Academy of Sciences of Belarus (1940), Doctor of Physico-Mathematical Sciences (1936), Professor (1936).
At the end of the 1920s, he formulated the general law of ferromagnetic phenomena - the law of anisotropy, which establishes the relationship between the magnetic and mechanical properties of ferromagnets. Revealed the temperature dependence of the anisotropy of ferromagnets. He created methods for analyzing ferroalloys and methods for finding defects in metal products. Author of works on the theory of chemical dynamics and chain processes, the statistical theory of dislocation, the theory of plasticity and strength.
Author of more than 200 scientific papers, incl. 4 monographs, 20 inventions.
State Prize of the USSR in 1941 for the creation of the theory of ferromagnetism and its practical application. State Prize of the BSSR in 1976 for the development and implementation of electromagnetic methods and non-destructive testing of mechanical properties of ferromagnetic materials and products. The prize of the German Academy of Sciences (1930), the Rockefeller Prize (1932), the Prize named after M.V. Lomonosov of the Academy of Sciences of the USSR (1953).
Awarded with the Order of the Red Banner of Labor (1951), medals.
