摘要：

We discuss a simple model of ferroelectric domain walls in terms of solitary-wave (kink) solutions of the equation of motion for the double-quadratic (DQ) chain. The response of the DQ kink to an external field is calculated and a very simple expression is obtained for the dynamic polarizability of the DQ kink. The simplicity of this model makes it more attractive than the usual ø4 model for studying the interaction of ferroelectric domain walls with external electric fields. © 1980 American Institute of Physics.
