Domain wall displacement at a distance l from equilibrium position by the action of external electric field .
Frequency dependence of real (solid line) and imaginary (dashed line) dielectric permittivity for different damping coefficient λ: (a) and (b) .
Behavior of real and imaginary dielectric permittivity under a bias electric field for different frequencies, for very small coercive field. (a) for different frequencies, (b) for , (c) for .
Ferroelectric hysteresis loop generated using Eq. (30) .
Behavior of curves due to hysteretic effect. Dispersion is notable for high frequencies( ).
curves involving polarization switching.
curves showing a overlap as Ec decreases.
curves for (circles) and the inverse quadratic model (solid line). Fitting was performed for the right hand side branch of the curve. All the measurements were performed at a frequency of 100 kHz (probing field).
hysteresis loop (solid line) and the reconstructed loop from curves (circles).
