Abstract
A new relaxation process in a nanoconfined ferroelectric liquid crystal (FLC) with high spontaneous polarization and short helical pitch is presented. In the cylindrical geometry of Anopore membranes, a collective dynamic process in the MHz region appears in the SmC* phase, instead of the phason (Goldstone) bulk relaxation. The relaxation frequency is temperature independent (except near the SmA/SmC* phase transition where an increase is observed). The origin of the process is discussed, the most consistent explanation assumes a relaxation of flexoelectric polarization near the splayed regions at the pore walls.
