AB - We report the observation of ferromagnetic resonance (FMR) in SrRuO3 using the time-resolved magneto-optical Kerr effect. The FMR oscillations in the time-domain appear in response to a sudden, optically induced change in the direction of easy-axis anisotropy. The high FMR frequency, 250 GHz, and large Gilbert damping parameter, α 1, are consistent with strong spin-orbit coupling. We find that the parameters associated with the magnetization dynamics, including α, have a nonmonotonic temperature dependence, suggestive of a link to the anomalous Hall effect. © 2009 The American Physical Society.
