Fields for resonance for in-plane FMR, , ; solid lines are Kittel fits. Inset: for all three FM/Cu, with (filled circles) and without (open squares) Pt overlayers.
Frequency-dependent peak-to-peak FMR linewidth for , as noted, films with Pt overlayers. Inset: Lineshapes and fits for films with (filled circles) and without (open squares) Pt overlayers, (right), CoFeB (left).
Inset: and for Py after linear fits to data in Fig. 2. Main panel: for Py, CoFeB, and Co. The slopes express the power law exponent
The additional nonlocal relaxation due to Pt overlayers, expressed as a Gilbert relaxation rate—thickness product for Py, CoFeB, and Co. Inset: Dependence of on spin diffusion length as tabulated in Ref. 17.
