Abstract

We investigate theoretically the generation of a spin current from a uniformly rotating body with impurity scattering based on the spin-dependent transport equation. If the cyclotron frequency is lower than the inverse of the relaxation time, the spin current is then created mainly in the radial direction when a weak magnetic field is applied parallel to the rotation axis. Spin accumulation is estimated by solving the spin diffusion equation. We show that the inverse spin Hall effect can be used to detect the spin current induced by rotation.
