Modeling of interactions in amorphous and nanocrystalline alloys with induced anisotropy

A modified version of the Stoner-Wohlfarth vector hysteresis model with a macroscopic mean field as well as a space and magnetization independent internal field is proposed. The model is applied to the description of hysteresis loops in soft nanocrystalline and amorphous materials with an induced an...

Summary:A modified version of the Stoner-Wohlfarth vector hysteresis model with a macroscopic mean field as well as a space and magnetization independent internal field is proposed. The model is applied to the description of hysteresis loops in soft nanocrystalline and amorphous materials with an induced anisotropy. A qualitative correlation between the induced anisotropy and the mean field term is found and discussed. Materials studied were nanocrystalline ribbon samples of a nominal composition Fe sub 73.5 Cu sub 1 Nb sub 3 Si sub 13.5 B sub 9 and amorphous ribbons of nominal composition Fe sub 64 Co sub 21 b sub 15 .
