3A15 競合誘電性液晶の臨界熱異常

The heat capacity has been measured near the smectic-A-ferrielectric phase transition in trustoelectric liquid crystals. A high precision ac calorimeter has been used for the measurement. In every case, a significant heat capacity peak was observed at the transition. The transition was found to be weakly first order. The heat anomaly showed a critical nature, which has been analyzed in detail using a power-law equation.
