Edmund Clifton Stoner

From Wikipedia, the free encyclopedia

Edmund Clifton Stoner (born October 2, 1899, in Surrey, England; died December 27, 1968 in Leeds, England) was a British theoretical physicist. He is principally known for his work on the origin and nature of magnetism, including the collective electron theory of ferromagnetism and the Stoner criterion for ferromagnetism.

[edit] Biography

Stoner began to attend Cambridge in 1918, receiving his undergraduate degree in 1921. After graduation, he worked at the Cavendish on the absorption of X-rays by matter and electron energy levels; his 1924 paper on this subject prefigured the Pauli exclusion principle. Stoner was appointed as a lecturer at the University of Leeds in 1924, where he became a professor of theoretical physics in 1939. Stoner did some early work in astrophysics and computed a limit for the mass of white dwarf stars in 1930. Most of his research, however, was on magnetism, where, starting in 1938, he developed the collective electron theory of ferromagnetism. Stoner retired in 1963. The E. C. Stoner building at the University of Leeds is named after him.^[1],[2],[3]

Stoner was diagnosed with diabetes in 1919. He controlled it with diet until 1927, when insulin treatment became available.^[1]
