An amorphous alloy which has a composition represented by the general formula (Fe.sub.1-a Co.sub.a).sub.1-x-y-z P.sub.x W.sub.y M.sub.z (where 0.9.ltoreq.a, 0.04.ltoreq.x.ltoreq.0.16, 0.005.ltoreq.y.ltoreq.0.05, 0.ltoreq.z.ltoreq.0.2, and M is one or more transition elements other than Fe, Co, and W. In a method for producing the amorphous alloy comprising at least Fe, Co, P and W by electrodeposition, the electrodeposition is performed in an acidic electrolyte bath which employs phosphorous acid and/or a phosphite as the P source and sodium tungstate as the W source, or in an acidic electrolyte bath which employs sodium phosphotungstate as the P and W source. The amorphous alloy which contains phosphorous as the metalloid element exhibits little reduction in saturation magnetization, and the crystallization temperature may be increased to above 450.degree. C.
