Abstract
Cobalt zinc ferrites with composition Co0.2Zn0.73Fe2O4, Co0.30Zn0.60Fe 2O4, Co0.37Zn0.51Fe2O4 and Co0.5Zn0.34Fe2O4, were prepared by solid st ate reaction technique in a single phase form. The electrical resistiv ity, X-ray density, bulk density and porosity of each sample have been measured. A change of slope has been observed in the Arrhenius plots indicating the presence of two regions of activation energy.
