Numerical study on the spin Seebeck effect in ferromagnetic insulators

Oe, Junichiro; Adachi, Hiroto; Takahashi, Saburo; Maekawa, Sadamichi

In this report, we show the numerical study on the spin Seebeck effect by considering the magnetization dynamics in the presence of thermal gradient. The dynamics of the magnetization is given by solving the Landau-Lifshitz-Gilbert equation. We introduce the random magnetic field originated from finite temperatures which depends on the position. We calculate the spin current driven by the magnon in ferromagnetic sample. We also discuss the spin pumping to the normal probe attached to the sample for detecting the spin current.
