Impact of Hydrogen Gas on the Inverse Spin Hall Effect in Palladium/Cobalt Bilayer Films

The influence of hydrogen gas absorption on the inverse spin Hall effect (iSHE) is measured in palladium/cobalt bilayer films. The iSHE is driven by ferromagnetic resonance in the Co layer and manifests as a dc voltage across the Pd layer. In the presence of hydrogen gas, the iSHE peak shifts downward in applied field together with the ferromagnetic… (More)
