Insight about spin Hall effects from spin pumping (presentation video)

We present measurements of the spin Hall effect using macroscopic spin currents generated from spin pumping. Measurements as a function of layer thickness enable the determination of the spin diffusion length, which is an essential parameter for the proper quantification of the spin Hall conductivity and the related spin Hall angle. Furthermore we discuss the temperature dependence of these measurements and how possible proximity effects may be reflected in the data.
