Abstract

A spin current generated by spin pumping in a ferromagnetic/nonmagnetic/ spin-sink trilayer film is calculated based on the spin pumping theory and the standard spin diffusion equation. By attaching the spin-sink layer, the injected spin current is drastically enhanced when the interlayer thickness is shorter than the spin diffusion length of the interlayer. We also provided the formula of the charge current which is induced from the pumped spin current via the inverse spin-Hall effect.
