Abstract

Driving the nonlinear magnetization dynamics in freestanding (100) iron membranes in a perpendicular magnetic field by the lowest-order high-Q acoustic cavity mode at ∼ 10 GHz frequency is simulated by numerically solving the Landau-Lifshitz-Gilbert equations. The analysis of the large-amplitude magnetization precession within nanosecond time window displays the transient chaotic magnetization dynamics induced by hopping between metastable energy minima on a complex anisotropy landscape. Fingerprints of transient chaos should be observable in femtosecond magneto-acoustic experiments with finite acoustic lifetimes.
