Outline of Final Research Achievements

Accurate structural study using synchrotron radiation X-ray diffraction was conducted for equilibrium state of strongly correlated electron system. We found an exotic spin-orbital magnetism in the hexagonal perovskite oxide Ba3CuSb2O9, which hosts a self-organized short-range structural order of a strong Jahn-Teller cation Cu2+. It was also possible to contribute to important new materials, such as new iron arsenic superconductors and a yellow-emitting phosphor, the Eu2+-doped chlorometasilicate Cl_MS, which can be used to create glareless white light-emitting diodes.
