Abstract
Nanocrystalline ferrites MFe2O4 (M = Ni, Co, Cu, Zn, Mn, Mg, etc.) are attracting the attention of researchers due to their utility in recording media, magneto-optics, spintronics, Ferrofluids, microwave devices, and so on. Ferrites are also utilized in gas and humidity sensors applications, anode material for a Li/Na-ion battery and electronic & magnetic applications. Combustion successfully generated cobalt ferrite (CoFe2O4) nanoparticles. X-ray diffraction (XRD) and infrared spectroscopy (FT-IR) were used to study the structural information. The crystallite size calculated by Scherer's formula is 14 nm based on XRD patterns. FTIR spectra indicate ferrite atoms in tetrahedral and octahedral positions, confirming the spinel phase. The electrical conductivity of CoFe2O4 nanoparticles at room temperature is 4.6 × 10-5 S cm−1.
