概要

• 論文の詳細を見る

• The temperature dependence of elastic stiffness constant C_<22> and ultrasound velocity of TGSe single crystals have been measured accurately near the ferroelectric phase transition. It is found that the anomalous part of the elastic stiffness constant ΔC_<22> and that of sound velocity are both proportional to log(T-T_c). The anomalous attenuation Δα^<1/2> in the paraelectric phase transition is also proportional to log(T-T_c).
