Fig. 3: FMR and voltage measurements.

a Schematic of the spin-pumping experiment in the FMR cavity where the sample is vertically shifted \(\Delta y=1\) mm away from the cavity center. b Typical FMR spectra recorded at \({\theta }_{H}={0}^{\circ }\) and \(9{0}^{\circ }\) and c angular dependence of the resonance magnetic field of the stack Al/NiFe/Al/WSe\({}_{2}\) (monolayer).
