Free oscillations in a ferroelectric liquid crystal
A description is given of experimental investigations in which free electromechanical oscillations are obtained for the first time in ferroelectric liquid crystals. © 1997 American Institute of Physics
Effect of elastic stresses on free oscillations in ferroelectric liquid crystals
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. © 1999 American Institute of Physics
