摘要：

In this paper, the effect of Ce3+ ions addition on the microstructure, electrical and magnetic behaviour of Cadmium doped Mn-Zn ferrites was investigated. A series having composition Zn(0.5)Mn(0.43)Cd(0.07)Ee(2-y)CeyO(4)(y = 0.0-0.7) was synthesized by wet chemical route. X-Ray Diffraction (XRD) analysis showed that prepared particles having size in nano-regime having cubic spinel structure with preferred (311) plane. Weakening of (311) plane intensity and emergence of secondary phase with Ce3+ ion concentration verified the substitution of Ce3+ ions in the spinel lattice of ferrite. The crystallite size varied between 46.4 and 67 nm as the concentration of Ce3+ ions increased from x = 0.0-0.7. Temperature and composition dependent electrical resistivity and activation energy values were calculated by current-voltage (I-V) characteristics in the temperature range 423-823 K by two probe method. It was observed that DC Resistivity and activation energy of synthesized nanoparticle ranges between 10(9) to similar to 10(19) Ohm cm and 11.78-2.56 eV respectively with increasing the concentration of Ce3+ ions. MH curves of prepared samples showed the paramagnetic nature of spinel feerites. The reported data suggested that these particles promising candidates for high-frequency applications.
