Nanocrystalline Ni0.5Cu0.5Fe2O4 was synthesized by sol–gel method with varying calcination temperature over the range of 500–1000. The powders obtained were characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). In addition, thermal analysis (TG–DTG–DTA) of the precursor was carried out. The study reveals the simultaneous decomposition and ferritization process at rather low temperature (280–350). Fo...
