Abstract

Method of manufacturing electromagnetic devices, of the type that comprise a ferromagnetic mass or body and at least one electrically conductive path magnetically coupled to the ferromagnetic body, where the body is a predominantly amorphous metal alloy, characterized in that the alloy is a low-alloy magnetostriction of the composition (CoaFebYc) and X1-y in which T is at least one species chosen from Ni, Cr, Mn, V, Ti, Mo, W, Nb, Zr, Pd, Pt, Cu, Ag and Au, X being at least one species chosen from P, Si, B, C, As, and Ge and between Al, Ga, In, Sb, Bi and Sn, and having a value of 0.7 to 0.9, a that of 0.7 to 0.97, b that of 0.03 to 0.25, and where a + b + c = 1.
