Paper Abstract

Investigations of a mixture possessing induced antiferroelectric phase are described. This mixture exhibited large thermal hysteresis of the transition between ferroelectric and antiferroelectric phases, which was demonstrated using dielectric and optical methods. Very slow kinetics (ranging from minutes to days) of the transition smectic C* $ARLR smectic CA* was revealed. The coexistence of ferroelectric and antiferroelectric states was noticed. In the investigated mixture the V-shaped switching was observed. The observed phenomena: hysteresis, slow kinetics and threshold-less switching are probably caused by competition of ferroelectric and antiferroelectric interactions acting between smectic layers.
