| Outline of Final Research Achievements |
The goal of this research project is to develop physical principles and material technologies enabling efficient and controllable thermo-spin conversion by combining spintronics with phononics. To accomplish this objective, we mainly investigated the spin Seebeck and Peltier effects, which refer to the generation of a spin current as a result of a heat current and vice versa, respectively. By systematically measuring the spin Seebeck effect, we demonstrated the independent control of magnon and phonon propagations by nanostructuring and the thermal spin-current generation by magnetoelastic coupling. Furthermore, we developed imaging techniques for thermo-spin effects by means of the lock-in thermography, and observed spatially-localized temperature modulation induced by spin currents. These achievements will provide a platform for next-generation spintronics combined with phononics.
