- 論文の詳細を見る
The dielectric, ferroelectric, DTA, thermal expansion, Raman scattering andultrasonic measurements of Li.Ge.0.. single crystal have been performed in awide temperature range including the phase transition point at 7L=283.5 K. Ithas turned out that Li.Ge.0.. undergoes a ferroelectric phase transition ofdisplacive-type and the transition is quite or alrnost contittuous. The Ramanspectra obtained support the idea that the phase transition is associated with asoft optic phonon at the Brillouin zone center of the space group Pbcn in theparaelectric phase.
