Phys. Rev. E 63, 061701 (2001) [8 pages]Disjoining pressure in free-standing smectic-A films and its effect on their reflectivityReceived 22 September 2000; revised 31 January 2001; published 11 May 2001 The results of calculations of a disjoining pressure and smectic layer spacings in free-standing smectic-A films (FSSAF’s) heated above the temperature of disappearance of the smectic order in bulk liquid crystal samples are presented. An effect of the disjoining pressure on the optical reflectivity of FSSAF’s having a different number of the smectic layers is investigated. The results of calculations are in agreement with results of experimental optical-reflectivity investigations of FSSAF’s. © 2001 The American Physical Society URL:
