Abstract

The cobalt substituted Li-Ni-Zn ferrites with the general formula Li0.5Ni0.15 Co0.1 Zn0.5 Fe2O4 were prepared using auto combustion method. Structural characterization of the samples was carried out using X-ray powder diffraction technique. The lattice parameter of the sample was found to be 8.376Å .The surface morphology of the ferrites was studied by Scanning Electron Microscopy (SEM) gives nanosized grains. Nanocrystalline nature of ferrites was also confirmed by Transmission Electron Microscopy (TEM). IR absorption spectra show two prominent bands characteristics of A and B site vibrations.
