Synthesis and Characterization of Cobalt Ferrite (Cofe2O4) Nanoparticles by Sol-Gel Autocombustion Method

Cobalt ferrite nanoparticles were synthesized by the sol-gel autocombustion method. To modify the features of the particles according to different requirements, the molar ratio of the metal nitrates to citric acid were varied. The final products obtained with different starting conditions were characterized through X-ray diffraction, Scanning Electron Microscopy and Energy Dispersive X-ray. Dielectric and magnetic measurements were finally carried out and the connection between structural and magnetic properties will be discussed.
