Rietveld refinement and magnetic characterization of nanospheric CoFe2O4 prepared under the effect of ethylene glycol and H2O
2024
Overview
Cobalt ferrite nanoparticles (CF NPs) have received appreciable interest recently due to their impressive chemical stability, high coercivity, and potent anisotropic magneto-crystalline. The Sol-gel method was appointed to manufacture Cobalt ferrites, utilizing ethylene glycol (Eth) and water (H

O NPs were entirely deliberated through techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR), and vibrating sample magnetometer (VSM). The XRD refinement through Rietveld methods utilizing Fullprof software proved that both samples crystallized into a spinel structure in cubic phase with space group Fd-3 m. The Williamson-Hall Plot was employed to determine the crystallite size (G) and microstrain (ε). The mean crystallite size was found to be 73 nm and 51 nm for CF-Eth and CF-H
