| Outline of Final Research Achievements |
In this study, we attempt to utilize the magnon in antiferromagnetic materials as the carrier of spin current, i.e. the flow of spin angular momentum. Through the measurement of spin Seebeck effect, we experimentally demonstrated that the antiferromagnetic magnon can indeed carry the spin current. In addition, by performing the propagating spin wave spectroscopy measurements, we revealed that the antiferromagnetic magnon has comparable magnitude of decay length with its ferromagnetic counterpart.
