Spin diffusion length associated to out-of-plane resistivity of Pt thin films in spin pumping experiments

Claudio Gonzalez-Fuentes, Randy K. Dumas, Bernat Bozzo +3

We present a broadband ferromagnetic resonance study of the Gilbert damping enhancement ($\Delta \alpha$) due to spin pumping in NiFe/Pt bilayers. The bilayers, which have negligible interfac…
