An experimental study of strange attractors at and beyond the period-doubling accumulation point is made for parallel-pumped spin-wave instabilities in a ferrimagnetic yttrium iron garnet disk. Singularity spectra are found to show a distinctive bifurcation, in the transition region leading to the growth of a high-dimensional attractor. A microscopic theoretical model well explains this phenomenon.
