In situ reverse co-precipitation synthesis and magnetic properties of CuO/CuFe2O4 nanocomposite

CuO/CuFe2O4 nanocomposite was prepared by reverse co-precipitation method. The microstructure and magnetic properties of the synthesized powders were characterized by X-ray diffraction, thermo-gravimetric and differential thermal analysis, Fourier transmission infrared spectroscopy, Brunauer-Emmett-Teller surface area analysis, scanning electron microscope, transmission electron microscope, and vibrating sample magnetometer. Magnetic measurements revealed that the saturation magnetization of samples increases with increasing calcination temperature. The increase of magnetic property of calcined powders can be explained as the results of the two important factors: formation of CuFe2O4 phase and grain growth of the nanoparticles. The results showed that the precipitates calcined at 900 A degrees C resulted in the formation of a crystalline CuO/CuFe2O4 nanocomposite with a maximum saturation magnetization of 21.2 emu g(-1).
