| Outline of Final Research Achievements |
In ferromagnetic metals, a spin wave, a collective motion of magnetic moments, strongly couples with conduction electrons. A novel method for spin-charge conversion based on the coupling is studied. We found an unconventional voltage related to injected spins in a ferromagnetic metal. The voltage measurements were done by changing spin polarization, magnetization, and electrodes directions. For further clarification, we considered use of microwave to excite spin waves and established a method for separating voltages due to microwave and others.
