G. Wiese, MULTISTABILITY AND CHAOS AT PARAMETRICALLY EXCITED SPHERICAL MODES INAN YTTRIUM-IRON-GARNET SPHERE, Journal of applied physics, 73(10), 1993, pp. 6819-6821
The different behaviors observed in different regimes of field of rece
nt high-power ferromagnetic resonance experiments on yttrium iron garn
et spheres within the coincidence regime of the first-order Suh1 insta
bility, which showed a complex multistable behavior beneath auto-oscil
lations, are examined on the basis of a detailed model which utilizes
the true eigenmodes of the sphere instead of plane spin waves.
