| Outline of Final Research Achievements |
We have succeeded in synthesis of four new double-perovskite oxides, each of which exhibits high degree of order in the arrangements of different transition-metal atoms, to reveal their ground-state magnetic order. Also, photoanodes consisting of epitaxial films of transition-metal oxide solid-solutions have been developed to demonstrate visible-light water oxidation enhanced via metal-to-metal charge-transfers. Moreover, using electrochemical Li-ion doping technique, we have realized reversible superconductor-insulator transition in a Li-containing titanate. These studies can be recognized to bring new trend in the framework of “oxide electronics”, and further development of functional oxide materials owing to their characteristic electronic structures is expected.
