Spin current generation due to mechanical rotation in the presence of   impurity scattering
  We theoretically investigate the generation of spin current from a uniformly rotating body with impurity scattering on the basis of the spin dependent transport equation. The spin current is created mainly in the radial direction when a weak magnetic field, where the cyclotron frequency is smaller than the inverse of the relaxation time due to the impurity scattering, 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.
