Abstract
Results on the effect of Mn, Sn, and Cr additions on the magnetic prop erties of positive magnetostrictive Fe79Si5B16 amorphous glass-covered magnetic wires are presented. Magnetic measurements performed on Fe75 Si5B16Mn4, and Fe77Si5B16Cr2 amorphous glass-covered wires show the ex perience of a large Barkhausen effect in these wires, but the switchin g fields are smaller than those of the Fe79Si5B16 ones. The additions also diminish the saturation magnetization of FeSiB amorphous glass-co vered wires. Measurements on samples after glass removal have been als o performed. The results are interpreted by taking into account the re duction in the strength of the magnetoelastic coupling between interna l stresses and magnetostriction due to the decrease of the magnetostri ction constant.
