One-step Synthesis of Cobalt Ferrite Nanoparticles by Co-Precipitation

In this study, cobalt ferrite (CoFe2O4) nanoparticles were prepared by single-step chemical precipitation method at room temperature for an hour. Cobalt ferrite nanoparticles were synthesized by cobalt sulfate, ferric chloride (III) and ammonium as deposition agent. Structure, particle size distribution and surface morphology of the nanoparticles were studied by X ray diffraction (XRD), transmission electron microscopy (TEM). Also, the magnetic properties of the samples were measured with a vibrating sample magnetometer (VSM). XRD spectrum clearly confirmed the formation of cobalt ferrite particles and lack of the presence of any other phase. The TEM images showed the uniform distribution of particle size. The average particle size was around 20 nm. The VSM results of cobalt ferrite nanoparticles approved the ferrimagnetism of the powders. VSM results of nanoparticles, cobalt ferrite property represents the ferrimagnetism particles.
