| Outline of Final Research Achievements |
We had explored the exotic electronic phases produced by an interplay between electron correlations and in 5d transition metal oxides and physics behind them. Spin-orbit coupling induced Heisenberg magnetism, Dirac semimetal-magnetic insulator transition and competition between spin-orbit coupling and orbital ordering were revealed. New compounds with a quantum spin liquid state, an exotic topological phase, an excitonic insulating state and spin detection function were discovered/designed.
