Abstract
CuFe2O4 nanoparticles have been obtained by heat treatment of coprecipitation product, which were synthesis by reaction of Cu2+ ions and Fe3+ in alkaline condition. The morphology and microstructure of the synthesized urchin-like superstructures have been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results show that the CuFe2O4 nanoparticles were polycrystal with cubic jacobsite structure and a size distribution from 20 to 40 nm. Magnetic properties have been detected by a vibrating sample magnetometer at room temperature. The nanoparticles exhibited a ferromagnetic behavior with the coercive force (Hc) value of 86.83Oe, saturation magnetization (Ms) value of 37.98 emu/g and remanent magnetization (Mr) value of 2.68 emu/g. The IR spectrum of peak at 586 cm−1 was corresponding to the vibration modes of CuFe2O4 nanoparticles.
