| dc.description.abstract | Nonlinear dielectric response of BaBi 4 Ti 4 O 15 ceramics synthesized via the conventional solid-state reaction route has been monitored over a wide range of electric field strengths (E 0 = 0.5-5 kV/cm). Dielectric permittivity was found to increase linearly within the range of applied field. Rayleigh relations were employed to interpret the nonlinear dielectric response and the contribution of irreversible domain wall motion to the macroscopic permittivity was separated. The values of room temperature Rayleigh dielectric coefficient (a) and relative initial permittivity (e'init# were found to be 2.28±0.02 cm/kV and 146.10±0.07, respectively. A reasonable agreement between the simulated and measured polarization-electric field #P-E# hysteresis loops was observed at an applied electric field of 5 kV/cm. |
