Abstract
Dynamics of director field switching in the vicinity of the SmA-SmC p hase transition is studied by means of light scattering. The resonance dependence of scattered intensity on the electric field frequency is observed. The resonance scattering disappears at lower temperatures. T he observed anomaly is consistently explained in the framework of the nonlinear kink switching model. The results of this work demonstrate t hat in the case of materials with high spontaneous polarization this m echanism is predominant.
