| Outline of Final Research Achievements |
Recently, spin wave (magnon) is attracting attention as a new carrier of information and energy in insulators. In this project, we focused on magnetic skyrmions (i.e. vortex-like swirling spin texture) characterized by nontrivial topology and symmetry, and explored their exotic magnon transport properties experimentally. As a results, we discovered (1) nonreciprocal magnon transport, (2) nonreciprocal phonon (quantized lattice vibration) transport, (3) a new material hosting extremely small skyrmion spin texture, and (4) magnon hall effect.
