| Outline of Final Research Achievements |
Spin hydrodynamic generation (SHDG) is generation of spin currents from fluid mechanical motion. The SHDG stems from a direct interaction between mechanical rotation and electron spins, called spin-rotation coupling. Especially in a fluid, vorticity, local rotation in a fluid, can be utilized as a source of the mechanical spin-current generation. In this study, we performed the SHDG measurement in a laminar flow, which is realized even in a micro or nano scale. By comparing results of the current study of the laminar-flow SHDG with that of the conventional study of turbulent one, we clarified SHDG’s properties especially due to the spin-rotation coupling. The results indicate the applicability of the SHDG to micro or nano scale physics, including spin-conversion physics by using the spin currents.
