Research Abstract

Our achievements are that 1) we have successfully developed a photocatalyst LiBi^<5+>O_3, where the photo-induced oxidization effect was found under illumination of commercially available white-fluorescent-light. 2) we have investigated the detailed electronic structure and physical properties of highly correlated ruthenates with (layered) perovskite structures using single crystals grown by floating-zone methods.
