Amorphous metallic alloys (AMA) based on iron [1], [2] and iron plus cobalt [3], [4], [5] are widely used for magnetic cores fabrication due to high saturation induction value Bs ≥ 1 T. Cobalt-based alloys at a sufficiently high concentration of iron (ratio of Co:Fe, at least 2:1, for example, 65% Co and 35% Fe) were studied by the authors of ...
