Outline of Final Research Achievements |
We succeeded in visualization of the middle-range order structure by improving the real space resolution of atomic pair-distribution function provided by synchrotron radiation source of high-energy X-ray diffraction. We observed not only local structures of relaxor ferroelectric materials and the nano sized ferroelectric crystals, in which ferroelectric mechanism inside the cluster was elucidated but also the cluster size itself.
