摘要：
Ni0.5Zn0.5Fe2O4 nanoparticles were obtained by complexation method using the following system: 0.5Ni(NO3)(2) - 0.5Zn(NO3)(2) - 2Fe(NO3)(3) - DMAE (where DMAE is dimethylaminoethanol). The complex precursor has been characterized by FTIR and thermal analyses. The formation of Ni0.5Zn0.5Fe2O4 nanoparticles was monitorized by thermal treatment of the complex precursor at 300 degrees C, 400 degrees C, 500 degrees C, 700 degrees C and 800 degrees C. The Ni0.5Zn0.5Fe2O4 spinel nanopowders have been investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). The magnetic properties investigation revealed significant differences regarding the saturation magnetization values of Ni0.5Zn0.5Fe2O4 samples obtained at different heating temperatures.
