ABSTRACT:
A thin amorphous alloy of cobalt, iron and phosphorus having good workability and the ability to be used as a soft magnetic material is formed by electrolytic deposition. The electrolytic bath has a pH of 1.0 to 2.2 and contains at least a divalent cobalt ion, a divalent iron ion, and phosphorous acid and/or a phosphite. The amorphous alloy contains at least 69 atomic percent cobalt, 2 to 30 atomic percent phosphorus and the iron/(cobalt+iron) atomic ratio is from 0.001 to 0.1. The alloy may be deposited on a working electrode having a chrome-plated surface with a center line average roughness of less than 1 .mu.m and may be peeled from the electrode to obtain a tape-shaped or foil-shaped product.
