采用电泳沉积（EPD）钴铁氧体颗粒和电镀金属钴相结合的方法制备了钴铁氧体镶嵌在金属钴基体中的纳米结构薄膜。利用金属Co作为软磁材料和Co铁氧体纳米颗粒（10-40 nm）作为硬磁材料。在该膜中，通过电泳沉积在Cu溅射基板上的Co铁氧体纳米颗粒的小簇嵌入在电镀金属Co中。在纳米结构膜的横截面图像中观察到由Co铁氧体纳米颗粒和金属Co组成的结构，如颗粒状。纳米结构的薄膜几乎没有表现出的磁性能给出的饱和磁化强度从金属钴和钴铁氧体纳米粒子的矫顽力。
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.
