NiFe thin films deposited by pulse reverse (PR) electrodeposition are promising candidates for the next generation of core magnetic material to be used in magnetic components operating at high switching frequency. The influence of PR electroplating on the structural, magnetic and electrical properties of NiFe is assessed by means of a design of experiment (DOE). Results are compared to NiFe alloys produced by direct current (dc) deposition from an identical electrolyte. The PR samples exhibit an increase in resistivity and relative permeability by a factor of 2 and 1.5, respectively, in comparison to the dc samples. The coercivity and saturation flux density of the PR samples are reduced by 37% and 5%, respectively.
