High spin-wave propagation length consistent with low damping in a metallic ferromagnet

We report ultralow intrinsic magnetic damping in Co(25)Fe(75) heterostructures, reaching the low 10(−4) regime at room temperature. By using a broadband ferromagnetic resonance technique in out-of-plane geometry, we extracted the dynamic magnetic properties of several Co(25)Fe(75-)based heterostruct...
