F. Rodelsperger et al., ROUTE OUT OF CHAOS BY HF PARAMETRIC PERTURBATIONS IN SPIN-WAVE INSTABILITIES, Journal of magnetism and magnetic materials, 140, 1995, pp. 1953-1954
Chaotic behaviour of a nonlinear system can be suppressed by fast para
metric modulation. Analytical and numerical investigations show that t
he increase of the modulation amplitude corresponds to an effective va
riation of the modulated parameter and results in a scenario 'out of c
haos'. Applying this method to a spin-wave experiment in YIG, the dyna
mics is changed from chaotic to periodic via type-III intermittency.
