The nanostructured film composed of the Co-ferrite embedded in the metal Co matrix was fabricated by the electrophoretic deposition (EPD) of Co-ferrite particles and electroplating of metal Co in combination. Metal Co as the soft magnetic material and Co-ferrite nanoparticle (10-40 nm) as the hard magnetic material were utilized. In this film, the small clusters of the Co-ferrite nanoparticles deposited by the EPD on the Cu sputtered substrate are embedded in electroplating the metal Co. The structure, like the granular, composed of Co-ferrite nanoparticles and metal Co was observed in the cross-section image of the nanostructured film. The nanostructured film barely exhibited the magnetic properties given the saturation magnetization from metal Co and the coercivity from Co-ferrite nanoparticles.
