Outline of Final Research Achievements

Under this research grant, we carried out the experiment in order to clarify the relationship between the structure and the external stimulus.
Using the second harmonic generation microscope, we confirmed that he polar nature of the ferroelastic twin boundaries in CaTiO3. Ferroelastic materials is fundamentally non polar and does not produce SH wave. However, the symmetry around the domain boundary is lower and it becomes polar. This idea also can be applied to antiphase boundary in antiferroelectrics. Since the width of domain boudary in ferroelastics and antiferroelectrics is much thinner than that of ferromagnetics, it is very attractive for the memory device application.
