Abstract
The role of effective anisotropy in nanocrystalline ferromagnets is in vestigated. These alloys are prepared by annealing amorphous ribbons a nd have excellent soft magnetic properties. A two-phase model is estab lished considering the role of the intergranular amorphous phase. The results indicate a strong dependence of effective anisotropy on the st ructure and magnetic parameters of the amorphous phase as well as on t he size of a grains. In view of the new model, the magnetic hardening beyond the optimally annealing temperature seems to be ascribed to the deterioration in magnetic properties of interfacial amorphous phase.
