ON-OFF INTERMITTENCY IN SPIN-WAVE INSTABILITIES

A particular case of chaos-to-chaos intermittency identified as on-off intermittency has experimentally been observed in a yttrium iron garn et sphere at high power ferromagnetic resonance. The theoretically pre dicted power law scaling with the exponent -1 has been detected in the dependencies of the mean ''laminar'' phase length on both static magn etic field and pumping microwave power. In the distribution of the lam inar lengths a -3/2 power law was observed close to the onset of inter mittency.
