Abstract

In the current paper, the nanoparticles of cobalt iron oxide doped by chromium (CIC) of (CrxCoFe2-xO4) formula were prepared by sol-gel method using the nitrate salts of the elements composed of this nanomaterial. The characteristic properties of CIC nanoparticles prepared were determined using X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) in addition to scanning electron microscopy (SEM) and also examination of the surface area (BET).
