Description
In this research, we report a study of nanostructured CuFe2O4 Spinel obtained by a method which makes uses of gelatin as an organic precursor. The structural and magnetic properties were investigated in function of calcination temperature. The precursor powders were calcined at 700 and 900 deg C to obtain spinel phase. Then were characterized using X-ray diffraction combined with the Rietveld refinement method, infrared spectroscopy (FTIR), and magnetic measurements. The X-ray diffraction patterns revealed the presence of an inverse spinel phase, corresponding to copper ferrite in all samples. Moreover, Fe2O3 and CuO phases were also identified. The results reveal that the calcination temperature strongly influences the magnetic properties of the prepared oxides. (author)
