Previous studies showed that the electrodeposition from baths consisting of trimethylamineborane and cobalt sulfate using a rotary electrode could yield Ni-Co-B ternary alloy films, and their alloying ratios and crystallographical structures could be controlled by changing the current density. In this study, the authors prepared multilayer films by periodically changing the current density, and investigated their structures and magnetic properties. The results were as follows:
1. In electrodeposition using a rotary electrode, periodic changes in current density and plating time were effective in controlling crystal size and film thickness to the levels required.
2. The films had soft magnetic properties. Controlling the crystallographical structure and thickness of the layers resulted in films with various soft magnetic properties.
