| Research Abstract |
An electric furnace was produced based on the delivered subsidy in FY 2007. Then, an electric furnace where the temperature can be controlled as precisely as possible was produced. The technique that used the developed electric furnace to experiment on the barium titanate (BaTiO_3) was developed in FY 2008. The domain observation around the phase transition temperature was performed in FY 2009. In strong dielectric domain of the BaTiO_3, it has been understood that the lattice strain has stabilized and the domain to the domain boundary.
