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 Fe₇₅Si₅B₁₆Mn₄, Fe₇₇Si₅B₁₆Sn₂, and Fe₇₇Si₅B₁₆Cr₂ 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
