スポンサーリンク
概要
- 論文の詳細を見る
Raman spectra of Sr.Nb.0 7 have been obtained between 45 K and 395 K. Alow-lying mode observed at a(bc)ct geometry softens toward the 117 K transitiontemperature and the square of the soft-mode frequency depends Iinearly ontemperature on both sides of the phase transition. The soft mode remains un-derdamped in entire range of temperature studied.
