概要
- 論文の詳細を見る
The heat capacity of a ferroelectrics consisting of two organic components having a centrosymmetric molecular shape, phenazine-chloranilic acid, was precisely measured by adiabatic calorimetry below room temperature. The paraelectric-ferroelectric phase transition was detected at 248K as a heat capacity anomaly. The excess entropy involved is consistent with the previously assumed displacive nature. In addition to the ferroelectric phase transition, two phase transitions were observed in heat capacity and dielectric constant at 136 and 146K.
