Abstract
Synthesization of zinc-substituted cobalt ferrites nano-particles Co1âxZnxFe2O4 (x=0.0-0.3) has been achieved by the sol/gel method. The characterization of the synthesized nano-particles has been done by X-ray diffractometry (XRD), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FITR). The relation between the composition and magnetic properties has been investigated by Magnetic Properties Measurement System (MPMS). The results revealed that the nanoparticles size is in the range of 11-28Â nm. It was found that the zinc substitution in cobalt ferrite increases saturation magnetization from 60.92Â emu/g (x=0) to 74.67Â emu/g (x=0.3). Nevertheless, zinc concentrations cause a significant decrease in coercivity.
