| Outline of Final Research Achievements |
An electroplating process of Fe-based magnetic films using a DES (Deep Eutectic Solvent) was developed. In electroplated Fe-Ni-Co films, high current efficiency (> 90%) was obtained in a wide composition range, and low coercivity values were observed in Fe-rich films. From the results of X-ray diffraction and TEM observation, we confirmed very fine structures of the Fe-rich films. As the effective magnetocrystalline anisotropy could be reduced by grain refinement, we considered that the low coercivity of the Fe-rich films is attributed to the grain refinement effect. From investigations on increase of deposition rate for the Fe films, we obtained a high rate of > 0.5 mm/h by the increased in the current density and the FeCl2 concentration in the bath. For electroplated Fe-Ni films, it was confirmed that glycine and ammonium amide sulfate effectively work to improve the surface roughness and the soft magnetic properties in Fe-rich films.
