Richard Milton Bozorth (10.04.1896-24.01.1981) was an American physicist and a member of the National Academy of Sciences. He was born in Salem. In 1922 he received the degree of Doctor of Philosophy at the California Institute of Technology. In 1923—61 he worked at Bell Laboratories (in 1926—46 as head of magnetic research).
His work was in the fields of solid-state physics, ferromagnetism, magnetic materials and the physics of metals. Independently of others he laid the foundations of the theory of domains, and he discovered a number of weakly ferromagnetic metals. He studied ferromagnetic anisotropy, magnetostriction, the Barkhausen effect and the annealing of iron-cobalt-nickel alloys in a magnetic field. He showed that a square hysteresis loop can be obtained. He made the first measurements of the magnetic susceptibility of the high-temperature superconductor Nb3Sn.
