Room-temperature electrical properties of the double perovskite material Sr2FeTiO6 synthesized by the solid-state method

The electrical properties of Sr2FeTiO6 have been studied at room temperature. Structural analysis via X-ray diffraction patterns reveals that Sr2FeTiO6 has a cubic perovskite structure with the pm3m space group. The electrical properties were presented as Nyquist and Bode plots. From impedance spectroscopy analysis, the Nyquist plot showed the presence of a bulk (grain) contribution. This was modeled by an equivalent circuit of the parallel combination of bulk resistance and capacitance. The Bode plot showed the presence of relaxation at room temperature.
