- 論文の詳細を見る
A systematic correlation is discovered for a number of ferroelectrics between transi-Lion entropy AS and the Rhodes-Wohlfarth ratio p./p, where p. is the effectivedipole moment determined from the Curie-Weiss constant assuming the existence ofpermanent dipoles, while p, is the saturation moment. The unified theoretical modelof ferroelectrics, which is capable of describing essential features of both displacive-type and order-disorder-type ferroelectrics, is shown to reproduce the above correla-lion strikingly well.
