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.
