In the present work, effect of co-doping rare earth (Re3+), La and Er cations on physical dielectric performance Cd-Zn spinel ferrites fabricated by sol-gel auto combustion method is reported. The prepared were doubly calcinated at 550 ℃ 750 for 2 hours 8 hours, respectively. obtained samples investigated using XRD, FTIR measurements. XRD powder patterns verified single-phase growth structure all as-synthesized with Fd-3m space group. results revealed that Lattice constant reduces increasing Er3+ concentrations, while crystallite size showed behavior concentration. existence two major absorptionbands i.e. low frequency bands in range 405-428 cm-1 high 523- which are evidence formation. LCR measurements used to investigate impact La3+ various parameters response frequency. Dielectric loss decreased incorporation Er3+, an increase ac conductivity was observed. observed properties reveal materials suitable candidates application high-speed microwave radio devices.
