概要
- 論文の詳細を見る
Lattice instability of the A_2BX_4-type crystal is studied on the basis of a discrete four sublattice model. The eigenfrequency and the associated eigenvectors of the dynamical matrix at general k values along the a' axis are analytically given. The relation between the wavenumbers at the incommensurate phase transitions, if any, and the interaction coefficients is clarified.
