摘要：

We study the contribution of stochastic motion of a domain wall (DW) to the dielectric ac susceptibility for low frequencies. Using the concept of waiting time distributions, which is related to the energy landscape of the DW in a disordered medium, we derive the power-law behavior of the complex susceptibility observed recently in some ferroelectrics below Curie temperature.
