概要
- 論文の詳細を見る
The successive phase transitions in (CH_3NH_3)_3Bi_2Br_9 (MABB) single crystal have been investigated by measuring of dielectric and elastic dispersion and Brillouin and Raman scattering. Softening of the elastic constant c_<66> and critical slowing down of the order parameter, which belongs to the E_g representation, have been found in the phase I. No optical soft mode has been observed. The phase transition from the phase I to the phase II has been discussed by the Landau theory.
