The invention refers to amorphous and nanocrystalline magnetic glass-covered wires. The wires consist of a metallic amorphous or nanocrystalline core with diameters by the order of 10.sup.-6 m, having compositions based on transition metal-metalloids and other additional metals and a glass cover, having a thickness of the wall by the same order of magnitude. The wires present high or medium saturation inducation, positive, negative or nearly zero magnetostriction and values of the coercive field and of the magnetic permeability in function of the request...
[ What is claimed is:] [1.]1. Amorphous magnetic glass-covered wires characterized in the fact that they consist of a metallic amorphous core with diameters ranging between 5 and 25 .mu.m of compositions containing 67 to 80 atomic % Fe,13 atomic % or less Si, 7 up to 35 atomic % B and 25 atomic % or less of one or more metals selected from the group consisting of Co, Ni, Cr, Ta, Nb, V, Cu, Al, Mo, Mn, W, Zr and Hf and a glass cover with the thickness ranging between 1 and 15 .mu.m, having 0.7 up to 1.6 T saturation inducation, positive magnetostriction r...
