FIG. 1.

Schematics of the antiphase (a), and the antiferroelectric Goldstone (b) modes in the relaxation processes of an antiferroelectric phase. The red dotted and black solid arrows indicate the spontaneous polarization and the direction of molecular motions, respectively. This directors shown by narrow lines lie in the smectic layer plane.

FIG. 2.

Chemical structure of MC881 (antiferroelectric liquid crystal) and MC815 (ferroelectric liquid crystal), and the spontaneous polarization (a), and tilt angle (b) as function of temperature.

Image of FIG. 3.
FIG. 3.

The relaxation frequency (a) and the dielectric strength (b) of pure MC881 as function of temperature. MM, AM, and SM denote the molecular, antiphase and soft modes respectively.

FIG. 4.

Relaxation frequencies of the antiphase (AF) and molecular modes (MM) versus temperature for different mixing ratios.
