| Outline of Final Research Achievements |
We obtained following results by the research aiming at exploration of the physics in insulator spintronics and construction of a new spin-utilization technology.
1. We succeeded in efficient spin injection into organic polymer conductors that are fundamental materials in present electronics industry. 2. We discovered novel magnetoresistive effect emerging in paramagnetic metal in contact with the magnetic insulator, and found the origin is the exchange of spin current at the metal-insulator interface. 3. We succeeded in spin injection into paramagnetic and topological insulator despite the former does not have long-range magnetic order and the latter is conductive at the very surface only. 4. The efficiency of spin current generation in the magnetic insulator is successfully controlled by applying a heat flow. Furthermore, novel non-reciprocal thermal spin current effect that the heat is displaced by spin-current conversely was also discovered.
