AC Voltage Generation by Spin Pumping and Inverse Spin Hall Effect
@article{Jiao2012ACVG, title={AC Voltage Generation by Spin Pumping and Inverse Spin Hall Effect}, author={Hu-jun Jiao and Gerrit E. W. Bauer}, journal={arXiv: Mesoscale and Nanoscale Physics}, year={2012} }
The polarization of the spin current pumped by a precessing ferromagnet into an adjacent normal metal has a constant component parallel to the precession axis and a rotating one normal to the magnetization. The former component is now routinely detected in the form of a DC voltage induced by the inverse spin Hall effect (ISHE). Here we compute AC-ISHE voltages much larger than the DC signals for various material combinations and discuss optimal conditions to observe the effect. Including the…

The inverse spin Hall effect (ISHE) arises from spin dependent scattering. It signifies a conversion of a longitudinal spin current into a transversal charge current. This enables spin current…

It is shown that a pure spin current can be produced in a solution-processed conducting polymer by pumping spins through a ferromagnetic resonance in an adjacent magnetic insulator, and that this generates an electric voltage across the polymer film.
