Synchrotron X-ray Study of Lattice Vibrations in CdCr2O4
スポンサーリンク
概要
- 論文の詳細を見る
Using inelastic x-ray scattering we have investigated lattice vibrations in a geometric frustrated system CdCr2O4 that upon cooling undergoes a spin-Peierls phase transition at T_{\text{N}} = 7.8 K from a cubic and paramagnetic to a tetragonal and Neél state. Phonon modes measured around Brillouin zone boundaries show energy shifts when the transition occurs. Our analysis shows that the shifting can be understood as the ordinary effects of the lowering of the crystal symmetry.
