Abstract :
Results on the effect of Mn, Sn, and Cr additions on the magnetic properties of positive magnetostrictive Fe79Si5B 16 amorphous glass-covered magnetic wires are presented. Magnetic measurements performed on Fe75Si5B16 Mn4, Fe77Si5B16Sn2, and Fe77 Si5B16Cr2 amorphous glass-covered wires show the existence of a large Barkhausen effect in these wires, but the switching fields are smaller than those of the Fe79Si 5B16 ones. These additions also diminish the saturation magnetization of FeSiB amorphous glass-covered wires. Measurements on samples after glass removal have been also performed. The results are interpreted by taking into account the reduction in the strength of the magnetoelastic coupling between internal stresses and magnetostriction due to the decrease of the magnetostriction constant
