Abstract
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 st epwise manner in the nematic temperature interval. The film thickness can be described by a power function of maximal temperature at which t his 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 f or the smectic-A-nematic phase transition.
