| Outline of Final Research Achievements |
The origin of various attractive properties in transition metal oxides has its root in the alignment of transition metal cations and their valence states. In view of creating oxides with new physical properties, the alignment of transition metal cations is controlled by making superlattice structures of perovskite oxide and subsequent reduction/oxidation reactions were deployed to adjust the coordination of oxygen anions. The orientation of precursor oxide whose cation network is in common with perovskite structure was controlled and an effective reaction system was developed to obtain at low temperatures perovskite oxides with unusually high valence cations.
