Free standing films of non-chiral liquid crystal compound have been studied by optical-reflectivity measurements. In the temperature range above the smectic-C smectic-A bulk transition the existence of macroscopic ferroelectric properties and orientation of the tilt plane parallel to an electric field is demonstrated.
