Abstract

A theory for exchange bias in ferromagnet/antiferromagnet bilayers is discussed. The mechanism depends on partial wall formation in the antiferromagnet, and it is shown that stability depends on the existence of an easy plane anisotropy and a minimum value of exchange coupling between the ferromagnet and the antiferromagnet, The effect of thermal fluctuations is also examined in terms of thermally activated processes. Consequences for field rate dependence of bias and coercive fields is described.
