dc.description.abstractConsidering a quadratic anharmonic model Hamiltonian and using double time temperature dependent Green's function method and Dyson’s equation treatment, expressions for the width in the frequency response for mixed perovskite type ferroelectrics have been obtained. Using the experimentally observed dielectric constant and loss tangent for Na1-xKxNbO3 [where x = 0, 0.4, 0.5], the temperature dependence of soft mode width in these samples at 10 and 100 kHz has been calculated. Anomaly has been observed in the behaviour of soft mode width, near the transition temperatures in these compounds.en_US
