Abstract

In this study, we use impedance spectroscopy in the frequency range of 5 kHz to 1 MHz and in the temperature range of 300-550 K in order to study the electrical conductivity and dielectric properties of Sr2FeTiO6. The dielectric constants show the classical type of the paraelectric state, with no pseudo relaxation peak. DC conductivity increases with increasing temperature according to the Arrhenius law, indicating a thermally activated process. The activation energy is evaluated based on the DC conductivity and using the Arrhenius equation. The relaxation mechanism is the same at various temperatures, as confirmed by the scaling of the imaginary part of the electric modulus.
