The Gilbert damping constant was investigated in polycrystalline Co₂MnSi Heusler alloy thin films by ferromagnetic resonance (FMR) technique. Samples were prepared using the magnetron sputtering technique on SiO₂ substrate and annealed at various temperatures to control the structure. The intrinsic Gilbert damping constant was obtained from angular dependences of peak-to-peak line widths fitting from FMR spectra using Landau-Lifshitz-Gilbert equation. Intrinsic damping constants of the polycrystalline Co₂MnSi films were almost independent of the annealing temperature.
