摘要：

Optical reflectivity of free-standing films at the smectic-A-nematic (Sm-A-N) phase transition has been studied. The Sm-A films thin in a stepwise manner in the nematic temperature interval. The film thickness can be described by a power function of maximal temperature at which this thickness is stable. The value of the exponent correlates with nu(\\) for the smectic fluctuations in the nematic phase determined by x-ray diffraction. The step-by-step thinning is a universal phenomenon for the smectic-A-nematic phase transition.
