Spin Pumping and Inverse Spin Hall Effect in Platinum: The Essential Role of Spin-Memory Loss at Metallic Interfaces

Through combined ferromagnetic resonance, spin pumping, and inverse spin Hall effect experiments in $\mathrm{Co}|\mathrm{Pt}$ bilayers and $\mathrm{Co}|\mathrm{Cu}|\mathrm{Pt}$ trilayers, we demonstrate consistent values of ${\ensuremath{\ell}}_{\mathrm{sf}}^{\mathrm{Pt}}=3.4\ifmmode\pm\else\textpm\...
