摘要：
CoFe2O4 nanoparticles (NPs) were synthesized by coprecipitation method using FeCl3·6H2O and CoCl2·6H2O as precursors. The synthesized conditions were optimized, such as added means of precipitator, quantity of precipitator, the mol ratio of Fe3+ to Co2+, reaction temperature and pH value. The synthesized material was characterized by XRD, TEM, FTIR, EDS, Raman and its magnetic properties were studied by VSM. The experimental results confirm that the sample is cubic spinel structure CoFe2O4 with a narrow size distribution and a good dispersion feature. CoFe2O4 NPs with well-controlled shape and size was obtained at 70 °C. The magnetic properties indicate superparamagnetic behavior and good saturated magnetization.
