Abstract

PURPOSE: To obtain an amorphous magnetic alloy material with superior wear resistance by adding a specified amount of a Pt group element, other transition element and a vitrifying element to an Fe group metal alloy consisting of Fe, Ni and Co.
CONSTITUTION: An alloy represented by formula I is melted and very rapidly cooled at 104W106°C/sec cooling rate to manufacture an amorphous alloy sheet suitable for a magnetic head. In formula I, p=4.0W7.0%, r=0W12%, p+q+r= 100%, M1 is one or more of Pt group elements such as Ru, Pd, Pt, Ir and Rh, M2 is one or more of IVbWVb group elements such as Nb, Ta, Ti, V and Zr, X is one or more of vitrifying elements such as Si, B, P, C, Ge, Sn, Ga, In, Sb and Al, a+b+c+d=100 atomic%, b=0.01W3 atomic%, c=0W4 atomic% and d= 20W26 atomic%.
