Interplay of large two-magnon ferromagnetic resonance linewidths and low Gilbert damping in Heusler thin films
Interplay of large two-magnon ferromagnetic resonance linewidths and low Gilbert damping in Heusler thin films
We report on broadband ferromagnetic resonance linewidth measurements performed on epitaxial Heusler thin films. A large and anisotropic two-magnon scattering linewidth broadening is observed for measurements with the magnetization lying in the film plane, while linewidth measurements with the magnetization saturated perpendicular to the sample plane reveal low Gilbert damping …
