摘要：
Electroclinic measurements are reported for a liquid crystal around the antiferroelectric smectic-CA*-"disordered" smectic-A phase transition. It was found that the spatially averaged tilt susceptibility exhibits a slope discontinuity at the transition, and that the extrapolated divergence temperature of the susceptibility is only 1.1±0.1°C below the Néel temperature. The relaxation times were found to be of the order of 1 μs. A simple mean-field model is presented. © 1995 The American Physical Society.
