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.
