摘要：

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 SmC-alpha* and SmC-gamma* 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: SmC-alpha*, the new antiferroelectric phase and SmCA*. The new antiferroelectric phase is different from the SmC* phase in that it exhibits much lower stability against an electric field.
