Abstract

The anisotropy characteristics of amorphous strips cut out from a Metglas 2714A ribbon and uniformly thinned by chemical etching are considered. Magnetic and electric properties are measured in the direction of the original ribbon axis and perpendicular to it, in the strip plane. Thinned samples are analyzed also after annealing above the Curie temperature, where annealing in the absence of an applied magnetic field and external stress gives rise to an unusual change in the easy axis direction. The results show that the defects mostly responsible for the anisotropy are prevailingly concentrated near the wheel-side and the air-side of the ribbon with different distributions on the two surfaces.
