Enhancement of Spin Pumping in ${\mathrm{Y}}_3\mathrm{F}{\mathrm{e}}_5{\mathrm{O}}_{12}/Pt/N{\mathrm{i}}_{81}\mathrm{F}{\mathrm{e}}_{19}$ Trilayer Film

We study spin pumping in a ${\mathrm{Y}}_3\mathrm{F}{\mathrm{e}}_5{\mathrm{O}}_{12}(\mathrm{YIG})/Pt/N{\mathrm{i}}_{81}\mathrm{F}{\mathrm{e}}_{19}(\mathrm{Py})$ trilayer film by means of the inverse spin Hall effect (ISHE). When the ferromagnets are not excited…
