摘要

We have already reported that a deep eutectic solvent is one of hopeful solvents to obtain an electroplated Fe-based soft magnetic film since the plating process shows high current efficiency. In this paper, we employed glycine as an additive to improve surface roughness and soft magnetic properties of electroplated Fe-Ni films. The coercivity of the Fe-rich films (>70 at.%) prepared from the glycine-used bath showed lower values compared with those for the no-glycine baths. From the evaluations for the surface roughness and the crystal structure of the as-plated Fe75Ni25 films, we considered that the reductions in the coercivity of the Fe-rich films for the glycine-used baths are attributed to the smooth surface and the reduction in the effective crystalline anisotropy by increase in the volume fraction of an amorphous magnetic phase in the film.
