Abstract
The effect of Nickel doped Cobalt ferrite nano particles Ni0.2CoxFe2-x04(x=0.1, 0.2, 0.3, 0.5) Created by sol-gel auto combustion technique by using citric acid as fuel. The single phase cubic structure form confirm by the XRD. The crystalline size calculated by FWHM of (311) plane using Scherer’s formula. The typicalsize of the crystalline sample varies in the order of nano regime. The structural and lattice parameter were obtained by XRD data. The surface morphology of Nickel doped Cobalt ferrites was studied by Field Emission Scanning Electron Microscope (FESEM), and Scanning Electron Microscope (SEM) images. The spherical particles with the average grain size 25.62nm to 33.69nm range are observed by FESEM images. Compositional stoichiometry was confirmed by X-ray photo electron spectroscopy.
