Magnetic nanoparticles (Fe3O4) were synthesized by the solvothermal method using FeCl3 center dot 6H(2)O and ethylene glycol as a reactant. Powder X-ray diffraction, FT-IR, TEM, SEM, and VSM were used to characterize the magnetic particles. The reacting factors, such as reacting time, the concentration of iron source and surfactant, especially the effect of NaAc center dot 3H(2)O, were studied. The results indicated that NaAc center dot 3H(2)O plays the role not only as a dispersant but also a structure-directing agent. The synthesized Fe3O4 particles showed excellent magnetic property, which made them have potential for application in magnetic nanodevices and biomedicine.
