Outline of Final Research Achievements

The purpose of this study was to achieve a quantitative understanding of chirality driven phenomena by introducing a concept of "chirality strength" that quantifies the chirality (handedness) of the crystal structure. We have successfully synthesized single crystals of isostructural chiral materials whose chirality strength can be tuned by a chemical substitution. We have found that the occurrence frequency of mono- or multi-chiral domains in these materials are clearly correlated with the chirality strength. We have also revealed that the temperature dependence of the chirality strength and an optical rotatory strength is correlated near a so-called gyrotropic structural transition, in which the chirality strength can be regarded as an order parameter. Moreover, we have demonstrated that the chiral materials discovered in this study are highly interesting systems in terms of their magnetoelectric properties, and obtained various results that exceed expectations.

Academic Significance and Societal Importance of the Research Achievements

本研究の主な成果は、結晶構造のカイラリティ(右手系と左手系)の度合いを定量的に表す「カイラリティ強度」なる概念を導入することで、カイラリティが関与する現象を定量的に理解できることを実際に示した点である。これにより、カイラリティ強度を「強磁性体における磁化」のような秩序パラメータとして位置づける研究が活発化すると期待され、カイラリティ関連物性の巨大化や新規機能の予測といった展開が見込まれる点で学術的意義を持つ。
