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 spectrosco...
