Abstract: Fe-Ni alloy films were prepared by electroplating in a plating bath containing a choline chloride and ethylene glycol-based deep eutectic solvent (DES). The Fe content of the electroplated films was found to vary from 0 at.% to 100 at.% and was dependent on the amount of Fe reagent in the plating bath. The composition of the electroplated films could be controlled easily by changing the composition of the bath. We observed bcc or fcc Fe-Ni crystalline phase in the electroplated films by X-ray diffraction and confirmed that magnetically soft Fe-Ni alloy films could be obtained from the DES-based bath. The current efficiency for the plating process was as high as >88% over a wide range of the Fe reagent concentrations. Therefore, we conclude that the DES is an attractive solvent for preparing the Fe-Ni alloy films.
