Suppression of Spin Pumping Between Ni${}_{80}$Fe${}_{20}$ and Cu by a Graphene Interlayer

Will Gannett, Mark W. Keller, Hans T. Nembach +2

We compare ferromagnetic resonance measurements of Permalloy Ni${}_{80}$Fe${}_{20}$ (Py) films sputtered onto Cu(111) films with and without a graphene (Gr) interlayer grown by chemica…
