Description
Summary:In this study, the characterization and magnetic properties of CoFe2O4 nanoparticles synthesized by co‐precipitation method were investigated. The calcined products obtained were characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X‐ray (EDAX), Fourier transformed infrared (FTIR) spectroscopy, and vibrating sample magnetometer. Crystallite size and phase composition were analyzed by X‐ray diffraction. Crystallite size and phase composition were analyzed by X‐ray diffraction. The average crystallite size of CoFe2O4 nanoparticles increased in the range of 15.85–32.14 nm with an increase in temperature from 500 to 700°C. It was observed that spherical CoFe2O4 nanoparticles were produced. Synthesis of CoFe2O4 nanoparticles was confirmed using XRD, SEM‐EDAX, and FTIR analyses. The effect of crystallite size, calcination temperature, and lattice parameter on saturation magnetization, remanent magnetization, coercivity, and magnetocrystalline anisotropy were investigated by vibrating sample magnetometer. As the crystallite size value increased, magnetocrystalline anisotropy also increased.
