| Research Abstract |
Development of the experimental technique on the visualization of anharmonic thermal vibration of atoms in the perovskite-type ferroelectrics was performed. Anisotropic thermal motion of atoms in Barium Titanate in the cubic phase was revealed. A new technique to observe the time-dependence of crystal structures was developed. The time-resolved motion of the Barium Titanate crystal lattice under the external electric field was successfully detected
