Magnetic behaviour of amorphous ribbons with creep-induced helical anisotropy and their fluxgate properties

We have induced a helical anisotropy distribution by a torsional and tensile stress annealing, in low magnetostriction amorphous ribbons. In this paper we report a theoretical study of predicted magnetization curves and the comparison with the experimental measurements. Further, we have studied some fluxgate properties (the feed-through, the offset and the noise) of ringcore sensors. The core material consists of metallic glass ribbon which has been heat treated in ways mentioned above. (C) 1998 Elsevier Science B.V. All rights reserved.
