Abstract

A new class of problems in disordered magnetism concerns interfacial or surface disorder coupled to structurally uniform adjacent layers. One example may be exchange anisotropy in ferromagnetic-antiferromagnetic sandwiches whose hallmark is a field-offset in the hysteresis loop. The phenomenon can arise from interfacial random fields causing the antiferromagnet to break up into Imry-Ma domains. A possibly related phenomenon is that of magnetically dead layers in systems like Fe on GaAs. In this case, spin-glass disorder and a domain structure it induces may create the appearance of a dead layer.
