摘要：

A binary liquid-crystal system possessing a tricritical point in its smectic-A-ferroelectric-smectic-C phase boundary is studied. The electroclinic tilt susceptibility and the spontaneous polarization are measured on both the first-order and the second-order side of the tricritical point. The experimental results are compared with predictions of a simple Landau model. Good agreement with mean-field behavior is found.
