Abstract

We have investigated the dielectric constant and capacitance of pure and tin-doped cobalt ferrite nanoparticles. The nanoparticles with spinel structure were synthesized by chemical co-precipitation method. The average particle size of the samples was 20 ± 2 nm. Room temperature impedance spectroscopy of the nanoparticles was performed in the frequency range of 100 Hz–2 MHz. The conductivity and dielectric response of the nanoparticles were found to increase with tin doping (20 % by atoms) in cobalt ferrite nanoparticles. The observed value of high-dielectric response at low frequencies has been attributed to the presence of grain boundaries in these nanoparticles.
