| 摘要 | The dynamic hysteresis of the first-order phase transition around the transition point T, in ferroelectrics is studied by investigating the dynamic response of the Landau-Devonshire (eta(2))(3) model to a time-varying external field of frequency f and amplitude E-0. It is revealed that the single-loop hysteresis as obtained above the upper critical point T+ and below the absolute instability point To shows dynamic behaviours very different from the double-loop hysteresis obtained between T-c and T+. An extensive calculation reveals a power-law scaling for hysteresis area as a function of E-0, while no reliable power-law scaling for the area as a function of f is available in the low-f regime. The scaling for the double-loop hysteresis seems not to fall into the same class as single-loop hysteresis. Furthermore,, the power-law exponents, if any, are somewhat temperature-dependent, but this dependence is very weak in the regime of low E-0 and high f. |
