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.[ref]
