| Outline of Final Research Achievements |
We have investigated effects of uniaxial stress on strongly correlated electron system. In the early stage of this study, we studied spin-lattice coupled systems, such as parent compounds of Fe-based superconductors, which originally have structural instability associated with magnetic and/or orbital orders, revealing that application of uniaxial stress significantly affects the crystal and magnetic structures. Subsequently, we applied the idea of uniaxial-stress-control of symmetry to various systems. We successfully demonstrated piezoelectric and piezo-magnetoelectric effects of spin origin in spin driven multiferroics.
