In this paper we prepared of stable strontium ferrite suspensions.The stability of the magnetic stron-tium ferrite particles was increased by the addition of a surfactant dodecylbenzene sulfonic acid(DBSA).The stable suspensions of the strontium ferrite particles were obtained in 1-butanol,and these were then used for a subsequent electrophoretic deposition.The stability of the suspension was analyzed by zeta potential measure-ments.The combination of DBSA with strontium ferrite was analyzed by infrared spectrum analyzer (FT-IR). The structure of the film was analyzed by X-ray diffraction (XRD).The morphology and thickness of the film were obtained by a field emission scanning electron microscope (FESEM)and the magnetic properties of the film were analyzed by a vibrating sample magnetometer (VSM).The results showed that:electrophoresis dep-osition of strontium ferrite film was feasible.The zeta potential of the suspension in 1-butanol was 87 mV.The thickness of the film by electrophoretic deposition was 9.44μm.The coercivity was 366.16 kA/m,with the sat-uration magnetization 42 A·m2/kg and the remanence ratio 0.56.The film can be potentially applied in circula-tors and isolaters at microwave frequencies.
