Outline of Final Research Achievements	This research, belonging to the 'Hypermaterials' project, has aimed at synthesizing previously non-existing groups of materials targeting magnetic, semiconductor, strongly-correlated (superconducting), and oxide hypermaterials. In the development of these new hypermaterials, we also adopted candidate compositions provied from the A03 group based on machine learning. The synthesized hypermaterials were provided to the A02 group for hypermaterials structural analysis and the A04 group for hypermaterials property measurements, elucidating both structure and properties. Furthermore, by collaborating with the A04 group to investigate the relationship between high-dimensional structures and physical properties, we contributed to the construction of high-dimensional materials science, which is the goal of the "Hypermaterials" project.

Academic Significance and Societal Importance of the Research Achievements	磁性準結晶をはじめとする本研究で行った新物質開拓は、既存の3次元結晶を前提とした物質探索の延長にはなく、人類が対象とし得る物質群の次元を超えた拡張を行ったものである。特に、従来の物質科学が立脚してきた「周期」という制約を取り払うことにより物質の新たな可能性を引き出したとともに、結晶では不可能な物性の実現に道を切り拓いたことに本研究の最大な意義がある。
