A <physicist> who, with <W. H. Meiklejohn>, reported <exchange bias> in particles combining a ferromagnetic metal and an antiferromagnetic oxide. The interface introduces a preferred magnetic direction through coupling between the two materials. This showed that the contact between different magnetic orders can change how a material reverses its <magnetization>, rather than merely adding their separate responses.<New Magnetic Anisotropy by W. H. Meiklejohn and C. P. Bean>[1956 discovery report, pp. 1413–1414: exchange anisotropy]{ref}
