| Outline of Final Research Achievements |
We have investigated the propagation of magnons (quanta of spin waves) in terms of the wave and particle pictures for achieving a magnonic device. In the terms of the wave picture, we have demonstrated the Snell’s law for spin waves, which indicates that the propagation direction of the spin waves is refracted at a step structure in thin ferromagnetic films. On the other hand, we find that the position of the magnons is changed owing to the Berry’s phase in the magnon band structure when they are scattered by the edge of the sample. Our results may lead to two-dimensional control of the magnons.
