| Outline of Final Research Achievements |
Domain boundaries in ferroic materials recently have been received lot of attentions because of their unique physical properties which only appear at the domain boundary. In this project, we used ferroelastic CaTiO3 (CTO) single crystal to observe the domain structure under the stress by using an optical second harmonic generation microscope. To realize the device using the domain boundary, it is necessary to control the domain boundary by external stimulus. This kind of experiment has not been reported yet. Our result reveals the possibility for future application using domain boundaries.
