Abstract

The random anisotropy model provides the theoretical basis for understanding the soft magnetic properties of amorphous and nanocrystalline ferromagnets. The arguments are surveyed, updated and illustrated in detail with the help of both an analytical model and numerical simulations. Questions how to extend the original model to a multi-phase system and how to include more uniform anisotropies are discussed. The results are related to the experimental findings for coercivity and permeability.
