摘要：

The electric field effects on an antiferroelectric liquid crystal at the phase transition was investigated. The microscopic observations were made for the measurements of the D-E hysteresis loop and apparent tilt angle. The tricritical point was found using phase diagrams. A soft mode inducing transition was observed from dielectric measurements. It was observed that the relaxation frequency depended upon the temperature.
