反強誘電-強誘電連続転移を示す液晶混合系に存在する2つの安定状態

抄録

Phase transition behavior of a V-shape switching binary mixture was studied using electric field induced birefringence, selective reflection, and optical rotational power measurements. The mixture was composed of ferroelectric MC452 and antiferroelectric MC881. This mixture has the ferroelectric SmC* phase at the higher temperature and an antiferroelectric phase at the lower temperature. The phase transition temperatures were approximately 85 and 74 degrees C for heating and cooling processes, respectively. The application of an electric field stabilized the ferroelectric phase down to 40 degrees C. The stabilization mechanisms of the higher phase is discussed.
