| Outline of Final Research Achievements |
Crystal chirality, a label defining the handedness of a system without improper mirror symmetry, is known as a source for a variety of functional properties of materials. In this research, we have studied the control of crystal chirality by an external field. We have shown that, when crystal chirality is coupled to other ferric order, the crystal chirality can be controlled through the field-induced switching of the ferroic domains. Moreover, we have successfully synthesized a new chiral material family. Then, we have introduced a concept of "qualitative chirality strength" and proposed that this concept can be useful for understanding chirality-driven material properties including the controllability of chirality.
