Abstract
Amorphous alloy for magnetic head core represented by the general formula, (Fe.sub.x Co.sub.1-x).sub.a Cr.sub.b Si.sub.c -B.sub.1-a-b-c, where the value of x is 0.04-0.07, the value of a is 0.73-0.75, the value of b is 0.005-0.03, and the value of c is 0.02-0.06. The present amorphous alloy has high permeability, high saturation flux density, low magnetostriction, and low magnetic after-effect at the same time, and has distinguished characteristics for magnetic head core.
