title: Electric field-induced cubic phase in 4'-n-docosyloxy-3'-nitrobiphenyl-4-carboxylic acid.
abstract: We examine the influence of an alternating-current electric field on the lamellar smectic C (SmC) phase of 4'-n-docosyloxy-3'-nitrobiphenyl-4-carboxylic acid, and the formation of a field-induced cubic (Cub) phase with optical isotropy was observed for the first time. The induction was realized down to a temperature 10 K below the zero-field SmC to Cub phase transition temperature (TSmC-Cub). The formation of the induced Cub phase gave rise to a gradual increase of the shear storage modulus, and the modulus recovered quickly in response to the removal of the field, which is of interest as future applications to the stress transferring device.
