| 摘 要： | 采用复合电沉积技术制备了磁性CoNiP-BaFe12O19复合薄膜, 分别用SEM、EDS、XRD、VSM 对复合薄膜进行了表征. SEM、EDS、XRD 测试表明BaFe12O19粒子被成功地掺入CoNiP硬磁薄膜中. 考察了基础电解液和复合电解液的电化学行为, 并探讨了BaFe12O19粒子和表面活性剂CTAB 的加入对薄膜中各成分相对含量的影响. 结果表明, 当表面活性剂CTAB 加入量为0.6 g·L-1时, 复合膜中BaFe12O19相对含量最高达20%. VSM 测试表明BaFe12O19粒子的掺入显著地增加了薄膜的矫顽力和剩磁比.

| Abstract: | CoNiP-BaFe12O19 magnetic composite thin film was prepared by composite electrodeposition and characterized by SEM, EDS, XRD, and VSM. The results indicated that BaFe12O19 particles were successfully embedded into the CoNiP hard magnetic thin film. The electrochemical behavior of the electrolyte was studied. The effect of incorporating of BaFe12O19 particles and surfactant CTAB on the mass fraction of the composition in composite thin film was investigated. A maximum mass fraction of 20%of BaFe12O19 was obtained when the concentration of the surfactant CTAB was 0.6 g·L-1. A clear enlargement of coercivity and the squareness ratio resulted from the BaFe12O19 particles being embedded in the thin film. |
