概要
- 論文の詳細を見る
An anisotropic softening of the acoustic mode in the ferroeJastic phase transi-tion of LaNb0. has been observed by the Brillouin scattering experiment. Thetransverse mode propagating along a direction deviated from the crystal axis by23' in the n6-plane shows a complete softening at the transition temperature T..The direction is parallel or normal to the ferroelastic domain boundary as pre-dicted by the phenomenological analysis of the phase transition from 4/m to 2/msymmetry. Thc temperature dependence of the elastic susceptibility is well de-scribed by the classical indices 7=7'=1 in both phases, suggesting a typicalproper ferroelastic transition.
