Abstract :

In the present paper, we report the synthesis of cobalt ferrite (CoFe2O4) nanoparticles using sol–gel method. The prepared samples were annealed at 700?C for 2 hrs. The average crystallite sizes of the nanoparticles were estimated using Debye–Scherrer’s equation and found to be 54.24, 57.46, 28.41, 29.62, 14.64, 26.68, 42.08, nm and 36.64 nm. SEM was used to study morphological variations and EDAX results showed that the compositional mass ratios were relevant as expected from the synthesis. FT–IR confirmed the presence of metal oxide bonds in all the calcined samples.Themagnetic properties of the produced powders have been studied using viating samplemagnetometer (VSM). TheSaturation magnetization and coercive field are strongly dependenton the various levels of doping concentrations. The saturation magnetizationwas decreased by increasing theFerrite content and increased by increasing thetemperatures from 700 ?C.
