概要
- 論文の詳細を見る
The temperature dependence of the Brillouin scattering spectra of K.SeOg wasobserved near the hexagonal-orthorhounbic phase transition point I"g (745.0 K).A softenaing of the longitudiuaal acoustic mode was found in the [l00[? direction oforthorhombic phase with increasing temperature toward T3. In th?e hexagonalphase, the frequency of the acoustic mode is nearly independent of temperature.
