| Abstract: | The Zn-substituted Fe_3O_4 composite magnetic fluids were obtained with different surfactants and solvens. Its specific saturation magnetizahon, the coercivity(Hc) and the size as well as the homogeneity of the composite magnetic particles were systematically measured. The influence of the Zn content and surfactant on their magnetic properties was explained. |

| Keywords: | Composite magnetic fluids Saturation magnetization(σs) Coercivity(Hc) |
