Abstract
The presence of three phases was found between SmA and the antiferroelectric SmCA * phase in optically active (R)-4-(1-methylheptyloxycarbonyl)phenyl 4'-octylbiphenyl-4-carboxylate. Two of these phases were identified as SmCα * and SmCγ * by the miscibility test. The remaining phase between these was confirmed to be another antiferroelectric phase from dielectric measurement and conoscopic observation. Thus, antiferroelectric order appears at least three times: SmCα *, the new antiferroelectric phase and SmCA *. The new antiferroelectric phase is different from the SmCA * phase in that it exhibits much lower stability against an electric field.Keywords
