概要
- 論文の詳細を見る
The phase transition in ammonium Rochelle salt is interpreted from the group-theoretical point of view following the Landau theory of phase transition and shown to be improper since it is induced by a two-dimensional representation at k=(1/2)b_1 which correctly describes the observed phase change from the space group D_2^3 to C_2^2. The expression of the free energy is given in terms of the doubly-degenerate transition parameter, besides the macroscopic polarization and deformation.
