Abstract
Polycrystalline Fe doped SmCrO3 perovskite ceramics were prepared by sol-gel route and characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), dielectric and Impedance measurements. Single-phase perovskite Fe doped SmCrO3 obtained has been confirmed from the XRD pattern with orthorhombic structure. The dielectric properties of perovskite Fe doped SmCrO3 ceramics were studied in the frequency range of 100Hz – 1MHz in the temperature range from 80 K to 300 K. These materials exhibited colossal dielectric constant value of ~ 104 at room temperature. The response is similar to that observed for relaxor-ferroelectrics. To get the detailed information, IS data analysis was performed.
