Physico-Chemical Characterization of Cobalt Ferrite Nano-Particles Synthesized Via Sol-Gel Method

Abstract

Cobalt ferrite (CoFe2O4) nano-particles were mainly been synthesized using that of the sol-gel method, aiming to mainly explore their structural, morphological, as well as the magnetic properties. Characterization techniques such as that of the  X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning form of  electron microscopy (SEM), and vibrating sample magnetometer (VSM) were hired. XRD evaluation showed the formation of a cubic spinel structure with a mean crystallite size of approximately 17 nm. FTIR spectra indicated characteristic metal-oxygen vibrations, while SEM photographs revealed almost round nano-particles with slight agglomeration. VSM measurements verified big magnetic homes, with a saturation magnetization of 84 emu/g. These findings propose the potential applicability of CoFe2O4 nano-particles in numerous technological fields.​
