摘要：

An electric field-temperature (E-T) phase diagram has been drawn for several binary mixtures of antiferroelectric liquid crystals using conoscopic observation. All the possible phases are SmA-SmC(alpha)*-SmC*-new antiferroelectric phase-new ferrielectric phase-SmC(gamma)*-new ferrielectric phase-SmC(A)*, some of which appear in the above regular order. Two Devil's staircases are necessary to elucidate systematic understanding of successive phase transitions among ferroelectric, ferrielectric and antiferroelectric phases: one is a staircase of SmC(alpha)*(q(T)) already discussed by Takanishi et al. and the other is a staircase of SmC(A)*(q(T)). Competition between an antiferroelectric interaction responsible for SmC(A)* and a ferroelectric one for SmC* is considered to stabilize a variety of phases, SmC(A)*(q(T)).
