R. Beccherelli et Sj. Elston, Investigation of the apparently thresholdless behaviour in the high temperature range of an antiferroelectric liquid crystal mixture, FERROELECTR, 246(1-4), 2000, pp. 949-956
In this paper we present a novel experimental investigation of the high tem
perature range of antiferroelectric liquid crystals. We find that in thin c
ells the SmC* phase is lost and a direct transition, apparently second orde
r, occurs between the SmC*(A) and the SmA*. This is accompanied by a large
electroclinic effect.
