摘要: The double perovskite oxide strontium cerium antimonate, Sr2CeSbO6 (SCS) is synthesised by solid state reaction technique. Thermal behaviour of SCS are investigated using thermogravimetric analyser and differential scanning calorimeter in the temperature range from 303 to 1500 K. Dielectric relaxation spectroscopy used investigate frequency dependent dielectric 100 Hz 1 MHz 703 electrical data analysed impedance formalism. mechanism sample modelled Davidson-Cole equation (modified Debye equation). frequencies corresponding maxima imaginary part at various temperatures found obey Arrhenius law with activation energy ∼ 0.15 eV. scaling suggests that describes same temperatures.
