CREEP-INDUCED ANISOTROPY IN AMORPHOUS GLASS-COVERED WIRES

Results on the creep-induced anisotropy in CoFeSiB amorphous glass-cov ered wires with nearly zero magnetostriction and in such wires after g lass removal are reported for the first time. The particular character istics of such magnetic materials determine particular aspects of this anisotropy induced by stress-annealing. For the experimental investig ation of the creep-induced anisotropy we used for the first time magne to-impedance-based measurements. Stress-annealed wires after glass rem oval behave similar to conventional in-rotating-water quenched amorpho us wires with the same composition. The glass-covered wires display a specific behavior originating in the presence of the glass cover.
