Magnetic properties of amorphous ferromagnetic alloys

Abstract For the application of amorphous, ferromagnetic alloys as soft magnetic materials a detailed knowledge of the domain structure, magnetization processes , the magnetic microstructure and thermodynamic properties is required. A review of the present state of the research work will be given. It is shown that the displacement of domain walls is described fairly well by the conventional potential theory developed previously for crystalline materials. Within the framework of the theory of micromagnetism the effect of quenching stresses on the domain structure as well as of short range stresses on the magnetic microstructure are discussed in detail.
