Pv. Dolganov et al., Optical reflectivity study of synclinic and anticlinic structures in thin freely suspended smectic films, EUR PHY J E, 3(1), 2000, pp. 7-10
Optical reflectivity studies have been conducted on freely suspended films
with synclinic and anticlinic structures. For the first time quantitative d
ata were obtained on orientational ordering in films with anticlinic struct
ure. In the same wide temperature range of more than 30 K we observed both
transverse and longitudinal ferroelectricity in the films of the same thick
ness. Equilibrium transition temperatures between structures with transvers
e and longitudinal polarization were above the bulk transition temperature
to the SmCA* phase. The molecule tilt was determined in superthin films wit
h synclinic and anticlinic ordering.
