Abstract

We apply nonlinear dielectric spectroscopy to an antiferroelectric liquid crystal MHPOBC at various smectic sub-phases. In the SmC* phase, the third-order nonlinear dielectric spectrum 3* is found to be composed of the contributions from ferroelectric soft mode and soft mode of the SmC* phase. The obtained spectrum is well ascribable by the theoretical one calculated by the Landau-type of phenomenological theory. In the SmC* phase, 3* shows a complicated form, and is different from one observed in usual ferroelectric liquid crystals. In the SmCFI1*( SmC*) phase, ferrielectric Goldstone mode with broad distribution of relaxation times is observed in both 1* and 3*.
