| Outline of Final Research Achievements |
In this research project, we studied following two subjects, 1) development of non-linear spin charge currents conversion and 2) exploration of novel interfacial spin-charge currents conversion. As a result, we discovered strong suppression of the spin Hall effect in the spin grass state. We found a strong enhancement of the spin Hall effect in superconductors and clarified the mechanism experimentally and theoretically. Apart from the above, we realized highly efficient spin-charge conversion via Edelstein effect occurring at the surface and interface states. More interestingly, Weyl type bulk symmetry was found to result in the charge-spin conversion where magnetization is induced by passing charge current. Furthermore we demonstrated experimentally as well as experimentally that the novel magnetic spin Hall effect could take place in Weyl antiferromagnets.
