Abstract

Spin wave instabilities in YIG spheres have been studied by FMR within the coincidence regime of the first-order Suhl instability. A complex multistable behaviour is observed, resulting in various types of auto-oscillations, sequences of bifurcations, intermittency and chaos. Our experimental results are discussed in terms of a multimode-model considering both spin-waves and magnetostatic modes.
