Abstract
In the present study, we report thesynthesis of cobalt ferrite nanoparticles using well known sol-gel auto combustion technique and design of magnetic parameters by titanium (Ti4+) doping. Cobalt ferrite is a promising candidate for magnetic recording, data storage and other nanoelectronics applications. The samples with generic formula Co1+xTixFe2-2xO4 (x=0.00, 0.10, 0.30 and 0.50) were prepared in thenanocrystalline form using the standard sol-gel autocombustion technique by taking citric acid as a fuel. The prepared nanoparticles were characterized by X-ray diffraction (XRD) technique and scanning electron microscopy (SEM) technique to know the phase and morphology respectively. The XRD patterns confirm the monophase cubic spinel structure of the samples and particle size obtained by Scherrer's formula was around 25 nm indicating the nanocrystalline nature of the prepared samples. The microstructural studies were investigated through scanning electron microscopy (SEM) technique. SEM confirmed the homogeneous and well-defined surface morphology in nano range. A careful designing and optimization of magnetic parameters are achieved by tetravalent non-magnetic Ti4+ doping in cobalt ferrite nanoparticles. The obtained magnetic parameters are useful for nanoelectronics applications.
