Abstract
Parallel-pumping experiments in YIG have been performed with modulated pumping fields. Above the spin-wave instability threshold, frequency locking states and a quasiperiodic route to chaos are observed. In a quasiperiodic state, an obtained attractor is a torus. Above a transition to a chaotic state, a breakup of the torus occurs. And a positive largest Lyapunov exponent, which is one of quantitative measures of chaos, is obtained in the chaotic regime.
