| Research Abstract |
We proposed new feature spintronics devices utilizing magnon (spin wave) and magnon current as a new spin source and elucidated the physics of spin transport in magnetic nanostructures using magnetic insulators. By using magnetic insulators, such as yttrium-iron-garnet (Y5Fe2O12:YIG), we explored novel spin transport phenomena, such as the spin Seebeck effect, involving magnon accumulation and magnon current and paved the way for development of new energy-saving spintronic devices.
