概要
- 論文の詳細を見る
Raman spectra of K3Co(CN). crystals have been observed at temperaturesdown to 30 K. The lowest frequency band in the low temperature phase, - 13cm ' at 30 K, softens to 5 cm ' near the transitic>n temperature ( - 63 K). Thissoft mode behavior shows that the phase transition is displacive one. Since nosoft optically active modes arc found in the high temperattu"e phase, the instabilityof the high temperature lattice is ascribed to the zone boundary phonon.
