Nickel-zinc ferrites are the magnetic materials that shows diverse industrial applications especially in the photo catalysis owing to their magnetic coactivity and eddy current loss with low value electrical resistivity with high value that affects and tailor these soft magnetic nano ferrites structural and morphological characteristics. In existing study, we have synthesized zinc doped nickel ferrites Ni1-xZnxFe2O4 nanoparticles (NPs) with variation in nickel and zinc concentration simultaneously as (x = 0.0, 0.2, 0.4, 0.6 ,0.8,1.0)) via Sol-Gel auto combustion technique. The structural analysis of the NPs was carried out by XRD technique. We compare our results with JCPDS #01-073-1963. From this study we conclude that the synthesized NPs are cubic spinel structure with preferential orientation along the (311) plane. D-spacing for (311) plane varies from 2.48 to 2.53 A0. We have determined the crystallite size using the Debay-Scherer Formula and we observed crystallite size in between the 22nm to 29nm. Investigations by XRD revealed that all the prepared samples demonstrate a pure phase. Alterations in the lattice parameters and micro-strain observed due to introduction of Zn in the crystal structure. Morphology of the synthesized NPs analyzed using the FESEM. We have observed that synthesized NPs are porous in nature. With concentration of nickel and zinc, this porosity varies. Stoichiometry of the NPs was studied with the help of EDS spectra. It confirms the presence of the nickel, zinc, iron and oxygen in the NPs. With change in the concentration, we observed the variation in the atomic % of Zinc and Nickel.
