ANOMALOUS TRANSITIONAL BEHAVIOUR IN MIXTURES OF LIQUID CRYSTALS : A NEW TRANSITION OF SA-SA TYPE ?

G. Sigaud , F. Hardouin , M. Achard , H. Gasparoux

The study of binary diagrams for which some features of the nematic-smectic A transitions are not in agreement with McMillan's theories is presented. A comparison of microscopic observations with enthalpic measurements leads to assume the occurrence of SA-SA transitions, the structure of smectic layers being either monomolecular or bimolecular.
