摘要（英）：

The invention aims at providing a FeOOH-ZnFe2O4 mixed magnetic fluid. The mixed magnetic fluid comprises a FeOOH magnetic fluid and a ZnFe2O4 magnetic fluid in the volume ratio of (1-2): (1-3), wherein the FeOOH magnetic fluid comprises alpha-FeOOH nano-particles and a HNO3 solution, the volume percentage of the nano-particles in the FeOOH magnetic fluid is 0.2-2%, and the molar ratio of H<+> to metal ions is (0.03-0.07): 1; and the ZnFe2O4 magnetic fluid comprises ZnFe2O4 nano-particles and the HNO3 solution, the volume percentage of the nano-particles in the ZnFe2O4 magnetic fluid is 0.2-2%, and the molar ratio of H<+> to metal ions is (0.03-0.07): 1. The mixed magnetic fluid has excellent magneto-optical properties. The invention further provides a preparation method of the mixed magnetic fluid. The preparation method has the advantages of simplicity, easiness in operation of the process, low cost of raw materials and low energy consumption.
