摘要：
A model of spin waves is developed for random anisotropy (RMA) magnets, where the deviations produced by the RMA are introduced. A negative shift in the magnon gap is found. The laws of approach to saturation of both magnetization and magnetostriction are of the form, a/√H + b/H, where the a and b constants are functions of the usual D/J ratio. © 1990.
