Polarization 'crossover' of field induced magnetic anisotropy in ferromagnetic amorphous alloys

Abstract

Field induced magnetic anisotropy data for amorphous Co66Fe4Mo2Si16B12 during polarization 'crossover' are reported. They were calculated from the magnetization energies of 12 mm diameter disk specimens cut from melt-spun ribbon. The magnitude of the anisotropy change produced and the kinetics of the change are in excellent agreement with a recent activation energy spectra model for structural polarization phenomena in amorphous metals. It is also shown that polarization 'crossover' can occur for any arbitrary anisotropy reorientation angle. It is expected that all other anisotropic properties of an amorphous alloy will display similar polarization 'crossover' phenomena. © 1986.
