Effect of Temperature on Fe₃O₄ Magnetic Nanoparticles Prepared by Coprecipitation Method

Abstract:

The Fe₃O₄ magnetic nanoparticles obtained by the aqueous coprecipitation method are characterized systematically using scanning electron microscope, X-ray diffraction and vibrating sample magnetometer. These magnetic nanoparticles are spheric, dispersive, and have average grain size of 50 nm. The size and magnetic properties of Fe₃O₄ nanoparticles can be tuned by the reaction temperature. All samples exhibit high saturation magnetization (M_s=53.4 emu·g^-1) and superparamagnetic behavior with a block temperature (T_B) of 215K. These properties make such Fe₃O₄ magnetic nanoparticles worthy candidates for the magnetic carriers of targeted-drug or gene therapy in future.
