Research Abstract

In this research project, we worked on properties of the spin wave that is driven in the presence of the temperature gradient or the local magnetic field. We clarified the origin of the spin Seebeck effect that is observed in the ferromagnetic sample with temperature gradient. We numerically simulate the dynamics of the magnetization by employing the Landau-Lifshitz-Gilbert equation. Our results showed that the exchange spin wave mode carries the spin current and results the finite bias voltage in the Pt probes. We found that the energy flow and the surface spin wave mode are driven simultaneously by the local magnetic field. We also found the chiral edge spin wave mode in magnetic crystal.
