Query: Free-Layer-Thickness-dependence of the Spin Galvanic Effect with Spin
  Rotation Symmetry   Spin-orbit coupling near the surface of a ferromagnetic metal gives rises to
spin-to-charge conversion with symmetry different from the conventional inverse
spin Hall effect. We have previously observed this spin galvanic effect with
spin rotation symmetry (SGE-SR) in a spin valve under a temperature gradient.
Here we show there are two processes that contribute to the SGE-SR, one of
which is sensitive to the free magnetic layer thickness, while the other only
depends on the interface of the free layer. Based on the
free-layer-thickness-dependent study, we extrapolate the spin diffusion length
of Py to be 3.9+/-0.2 nm. We also propose that the SGE-SR can help to
quantitatively study the spin Seebeck effect in metallic magnetic films.
