Abstract
We report X-ray layer spacing, dielectric constant and high pressure measurements on a compound that exhibits the following sequence of phase transitions: smectic A-ferroelectric smectic C∗-ferrielectric smectic Cy∗-antiferroelectric smectic CA∗ -hexatic antiferroelectric smectic IA∗-crystal K. The pressure-temperature diagram shows two three-phase meeting points, which are topologically consistent with critical end points, and reentrant behavior of the C∗ and C∗ phases as the pressure is varied at constant temperature.
