Abstract :
In this paper, the aim is to analyse the influence of tensile stress (applied during treatment as well as during measurements) on /spl lambda/s value, for positive, negative and nearly zero magnetostrictive Fe/sub 72.5-x/Co/sub x/Si/sub 12.5/B/sub 15/ glass-covered amorphous wires. During treatments, the current density, tensile stress and annealing time values were varied up to 250 X 10/sup 6/A/m/sup 2/, 500 MPa and 250 minutes respectively. The amorphous state was examined by X-ray diffraction.
