PURPOSE:To reduce the absolute value of magnetostriction of an amorphous Co- Nb-Zr alloy, to increase the saturation magnetic flux density, and to improve the heat resistance and corrosion resistance by substituting Cr, Mo, V, Ta or W for part of Nb in the alloy. CONSTITUTION:Cr, Mo, V, Ta, or W is substituted for part of Nb in an amorphous magnetic Co-Nb-Zr alloy to provide a composition represented by a formula Coa(Nb1-xMx)bZrc [where 81<=a<=95(atom%), 2.5<=c<=5, a+b+c=100, c/(b+c)>0.25, when M is Cr, Mo, V or Ta, 0<x<=0.5, and when M is W, 0<x<= 0.2]. The resulting amorphous magnetic alloy having low magnetostriction is suitable for use as the material of a magnetic head having high performance formed by a thin film forming technique such as sputtering. |
