Abstract

Transverse pumping at the first-order Suhl instability in YIG has been performed at a pumping frequency of 3.3 GHz at 4.2 K. Above the spin-wave instability threshold, period-doubling cascades and chaotic auto-oscillations are observed. The largest Lyapunov exponent as a function of driving microwave power shows the characteristics of the onset of chaos. The fractal structure is elucidated by a correlation dimension and an f(α) spectrum.
