  • Nowadays the magnetic nanoparticles gained much interest of researchers due to their wide range of applications on account of their smaller size and large surface to volume ratio. Hence, the present investigations deal with the effect of substitution of tetravalent (Ti4+) ion in cobalt ferrite matrix on structural and electric properties. The samples with generic formula Co1+xTixFe2-2xO4 (x=0.00, 0.10, 0.30 and 0.50) were prepared in nanocrystalline 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.The twoprobe technique was employed to measure the electric properties of the investigated samples.The XRD spectra confirm the cubic spinel structure of the samples without any impurity and particle size obtained by Scherrer’s formula gives confirmation of nano size of synthesized samples. The Arrhenius plots show semiconducting behavior of all the samples and the DC resistivity improved by substitution of tetravalent (Ti4+) ion in cobalt ferrite. The requirements of electronic industry may fulfil with the synthesized nanoparticles. The increased DC resistivity in cobalt ferrite with Ti4+ substitution can be useful for the energy storage applications.
