Sergei Vonsovskii
Vonsovskii, Sergei Vasil’evich
Born Aug. 20 (Sept. 2), 1910, in Tashkent. Soviet physicist. Academician of the Academy of Sciences of the USSR (1966; corresponding member, 1953). Chairman of the presidium of the Urals Scientific Center of the Academy of Sciences of the USSR (1971). Hero of Socialist Labor (1969).
Vonsovskii graduated from Leningrad University in 1932. From 1932 to 1939 he worked at the Urals Engineering Physics Institute in Sverdlovsk and from 1939 to 1947 at the Institute of Metallography, the Physics of Metals, and Metallurgy of the Urals branch of the Academy of Sciences of the USSR. Since 1947 he has been with the Institute of the Physics of Metals of the Academy of Sciences of the USSR. His principal works deal with the theory of the magnetic and electric properties of metals and semiconductors, the theory of ferromagnetism, and the theory of superconductivity. He proposed the so-called polar model (with S. P. Shubin) and the s-d model of ferromagnetics. On the basis of these models, Vonsovskii and his colleagues have constructed a general theory of ferromagnetics close to the Curie point, and he has explained fractional atomic moments and some characteristics of kinetic properties as well as taken into account the effect of the multiplicity of the magnetic ions of these substances. Vonsovskii has been awarded the Order of Lenin, two other orders, and various medals.
