  Abstract
  Indium Zinc Titanate, In2(ZnTi)O6 (IZT), a double perovskite is synthesized. The field dependence of the conductivity and the dielectric response of the sample are measured in a wide frequency and temperature. It is observed that, the dielectric constant decreases with the increase of frequency. The frequency dependence of the loss peak is found to obey an Arrhenius law with activation energy of 0.73 eV. An analysis of loss factor with frequency is performed by using the scaling behaviour of the dielectric loss spectra. The complex impedance plot of the sample confirms that the polarization mechanism in IZT corresponds to bulk effect of semiconductor IZT particles. The relaxation mechanism is discussed in the framework of impedance and modulus formalism. The full potential linearized augmented plane wave method is employed to study the ground state properties.
