A series of Co1-xZnxFe2O4 ferrites with x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5 were synthesized using the standard double sinteringceramic technique. The single-phase cubic spinel structure of the samples was confirmed from the X-ray diffraction patternsand the sharp high intensity peak revealed that the samples are in good crystalline form. The lattice parameters were observedto increase with the increasing of Zn concentration. By increasing the concentration of Zn content, a significant increase in thedensity and a subsequent decrease in porosity and grain size were observed. The dielectric constant (ε′) of the sample is foundto decrease with the increase in frequency. Dielectric relaxation peaks were observed for the frequency dependence of dielectricloss curves. The dc resistivity at different temperatures was studied and all the samples were of semiconductor nature. Thesaturation magnetization was found to be reduced as the Zn substitution was increased and consequently permeabilitydecreases.
