The new phase appears at 3 GPa and coexists with the CDW state up to 6 GPa, at least. The volume ratio between the two coexisting phases measured by Raman scattering spectroscopy changes continuously with pressure. The result is discussed in terms of the theoretical approach to the polymorphic phase transition developed recently by Bassler, Sasaki, and Griffiths. It is suggested that kink solitons play an important role in this phase transition., 擬一次元白金錯体の高圧光効果を従来よりもさらに高い圧力領域にまで拡張して測定した結果、およそ3 GPaで擬一次元結合の電荷密度波状態に、通常の圧力誘起構造相転移では理解できない、新種の相転移が生じることが見出された。この相転移の特徴は、低圧相が消失せず、6 GPa以上の圧力下でも可逆的に高圧相と共存することである。実験データの解析より、理論的にしか知られていなかった新しいタイプの臨界点(ウプシロン臨界点)がこの物質系で実現している可能性の高いことを論考した。, http://link.aps.org/abstract/PRL/v68/p3056},
