Abstract
Cobalt-substituted magnetite CoxFe3-xO4 nanoparticles were synthesized using a sol-gel auto-combustion method using citric acid as a fuel. The samples were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) spectroscopy, optical ultraviolet-visible (UV-Vis) spectroscopy, and vibrating sample magnetometer (VSM). XRD studies revealed cobalt replacing iron, forming a single phase with a crystalline size of 17–25 nm. FESEM and FTIR spectra showed a metal–oxygen bond, while UV-Vis spectra showed absorbance spectra and Kubelka–Munk theory. Magnetic properties were studied using VSM, revealing increased saturation magnetization and a constant squareness ratio, confirming the single domain of cobalt-doped Fe3O4 nanoparticles. These nanoparticles have potential applications in spintronics, nanoscale devices, and supercapacitors.
