Abstract
Ferrites are renowned for their extensive use in a variety of industries, from manufacturing to the biomedical field. In the current study chromium substituted cobalt ferrite nanoparticles (CoCrxFe2-xO4,x = 0, 0.25, 0.5, 0.75, and 1) were synthesized by utilizing the sol–gel auto combustion method. Various analytical tests confirm the effect of Cr doping concentration on cobalt ferrites. The structural and morphological analysis of samples were done using X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) respectively. The samples' pure spinel structure was confirmed by XRD analysis. Magnetic characterization at room temperature and low temperature were carried out using Quantum Design's PPMS. The dielectric properties of the samples were examined using a Hioki 3532 LCR hitester. The results demonstrate the effect of chromium substitution in cobalt ferrites and suggest the possible uses of the prepared samples.
