Abstract

The effect of a platinum (Pt) capping layer on the magnetization dynamics in polycrystalline yttrium iron garnet (YIG) films of various thicknesses has been studied in order to understand the influence on the Gilbert damping of YIG films by the spin-pumping at the YIG/Pt interface. The Gilbert damping in each YIG film with the Pt capping layer is found to be much higher than that of the YIG film without the Pt capping layer, as expected due to the spin-pumping effect. In comparison with the samples without capping layer, an enhanced value of interfacial spin mixing conductance can also be observed for films with the capping layer. These results demonstrate the existence of spin-pumping effect at the YIG/Pt interface which plays an important role for the enhancement of Gilbert damping.
