Free-standing films of nonchiral liquid crystal compound are studied b
y optical reflectivity measurements. The existence of macroscopic ferr
oelectric properties and orientation of the tilt plane parallel to an
electric field in the temperature range above the smectic-C-smectic-A
bulk transition is demonstrated. (C) 1998 American Institute of Physic
