| Abstract | ||||
| The effect of γ-irradiation on the structural and the electrical properties of rare earth ferrite of the general formula Co0.5Zn0.5CeyFe2-yO4 (0.0≤y≤ 0.2) is discussed. X-ray diffraction pattern of irradiated and un- irradiated samples showed the formation of cubic spinel structure. The obtained data show that the electrical conductivity ln σ as well as the dielectric constant ε` are highly dependent on both Ce ion concentration and radiation dose. The number of ferrous ion at octahedral sites play a dominant role in the change of the crystal size due to irradiation effect. All samples exhibit a change in slope of the conductivity versus inverse temperature giving two regions with different conduction mechanisms. | ||||
