Abstract

Magnetization curves of a ferromagnetic film on an antiferromagnetic substrate are investigated with allowance for the frustration caused by roughness of the interface. The conditions for unidirectional anisotropy are determined, and its dependence on the degree of roughness of the film-substrate interface is found.
