Article Description

CoFeO nanoparticles (NPs) were synthesized by coprecipitation method using FeCl·6HO and CoCl·6HO as precursors. The synthesized conditions were optimized, such as added means of precipitator, quantity of precipitator, the mol ratio of Fe to Co , 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 CoFe O with a narrow size distribution and a good dispersion feature. CoFeO NPs with well-controlled shape and size was obtained at 70 °C. The magnetic properties indicate superparamagnetic behavior and good saturated magnetization. © Wuhan University of Technology and Springer-Verlag Berlin Heidelberg 2011.
