Through the inverse spin Hall effect, spin-pumped currents from a Py(Ni80Fe20) layer are converted to direct current (dc) voltages in an adjacent platinum (Pt) layer, which adds to dc voltages generated by the spin rectification effect originating from anisotropic magnetoresistance, ordinary and anomalous Hall effect in the permalloy (Py) layer. Based on a shorted microstrip fixture, we perform angular measurements of rectified dc voltages in a Py(Ni80Fe20)/Pt bilayer to simultaneously separate spin pumping-induced inverse spin Hall voltages from spin-rectified voltages. A systematic approach to accurately determine the spin-Hall angle of Pt is presented.
