- 論文の詳細を見る
It was experimentally confirmed by observations of stress-strain hysteresis loop that the room temperature paraelectric phase of NH_4HSO_4 is ferroelastic. This observation undoubtedly suggests the existence of the prototypic crystal structure from which the paraelectric-ferroelastic phase is derived by the phase transition. By adopting the Pnma phase as a prototype the phase transitions to the room temperature B2_1/a and then too the ferroelectric Ba phase are group-theoretically analysed. The results are in satisfactory agreement with observations.
