Electroless-plated CoB films were plated from the bath with dimethylamineborane (DMAB) as a reducing agent. Magnetic properties of the films changed widely with changes in the concentrations of complexing agent in the bath, such as ammonium sulfate or sodium tartrate. Among them, film with the lowest coercivity was obtained from the bath containing 0.3 mol dm-3 of sodium sulfate and 0.55 mol dm-3 of sodium tartrate. The structural analysis of this film clarified by electron microscopy that the film consists of fine-particulated hcp crystalline with high crystallinity.
