Research Abstract

The research program “Frustration and Relaxors” is one of the research projects of the Grant-in-Aid for Scientific Research on Priority Areas “Novel States of Matter Induced by Frustration”. We developed new relaxor materials including lead-free ferroelectrics, clarified wide time-space structure in relaxor ferroelectrics, and proposed a minimal model for describing the range from the relaxor to the ferroelectrics. Therefore, our research made an important contribution to the basic research in relaxor systems and provided a new viewpoint to the conventional research field in frustrated systems.
