Fe-B amorphous alloy film was formed by means of contact plating method, in which Cu foils in contact with Al wires were used as substrates. Local battery configuration of the Cu foil anode and the Al wire cathode was responsible for film formation. The boron content in film was controlled from 0at% to 28at% by changing the KBH4 concentration in the bath. The bath temperature strongly affected the crystallographic structure of resultant films. Fe80B20 amorphous films required a bath temperature below 40°C. Film structure and composition also affected magnetic properties. Film coercivity below 17Oe was also observed.
