摘要:
Nickel-iron-boron alloy magnetic films containing from 0.1 to 2.0% boron by weight and from 17 to 27% iron by weight are electrolytically deposited using a bath having a pH of 2.5 or less, and containing a borane reducing agent. Thefilms have a high resistance to corrosion and a coercivity less than 0.1 Oe in films 3000A thick.
