| Abstract: | It is shown experimentally that an elastic mechanical stress in a crystal structure is a necessary factor for the appearance
of free oscillations of the director of a ferroelectric liquid crystal. Such a mechanical stress arises as a result of internal
textural perturbations in the presence of regions with a different orientation of the director or is produced by external
pressure applied to one of the cell plates in the appropriate direction.
