Electroless Ni-Fe-B alloy plating solution using DMAB as a reducing agent

This paper describes the development of an electroless nickel iron boron plating solution using dimethylamine borane (DMAB) as a reducing agent. Two complexing agents, namely sodium citrate and sodium tartrate, are used. Satisfactory stability of the solution and relatively high deposition rate are achieved with this solution. Soft magnetic films having a coercive force of 20 A/m (0.25 Oe) are deposited from the solution.
