| dc.description.abstract | Considering a quadratic anharmonic model Hamiltonian and using Green's function and Dyson’s equation technique, expressions for the width in the frequency response for mixed perovskite type ferroelectrics and soft mode frequency have been obtained. Using the experimentally observed dielectric constant and loss tangent for Na1-xKxTaO3 (where x = 0, 0.2, 0.4, 0.5 and 0.6) the temperature dependence of soft mode width and frequency in these samples at 10 kHz has been calculated. | en_US |
