A series of the ferrite system Mn1-xZnxFe2O4 (x = 0.0, 0.05, 0.1, 0.15, and 2.0) were prepared by the standard ceramic method. The X-ray diffraction patterns confirmed the formation of single phase cubic structure and shows also that the lattice constant decreases with increasing Zn content. The effect of Zn+2 ion concentration on the structural and the electrical properties of the investigated samples are studied. The most important result of γ-irradiation on the electrical properties is the variation of change ratio Fe2+ Fe3 + e− on the octahedral site leading to an increase in the conductivity as well as the dielectric constant.
