抄録

Intermittent behavior in magnon systems is studied through ferromagnetic resonance experiments using a sphere of yttrium–iron–garnet (YIG) under X-band microwave pumping. Intermittency is observed near the microwave power of the onset of the second-order Suhl instability. Based on Kullback–Leibler information theory we considered two models of the laminar length distribution: an exponential model and a power law model. At low power, the distribution follows an exponential model, indicating a predominantly Poisson process, transitioning to a power law model at higher power, indicating chaotic dynamics. This transition suggests that an orderly state arises due to magnon–magnon interaction from the initially disordered state (random process) with increasing microwave power.
