Abstract
The dynamic behavior of magnetic moments in a two-layer magnetically couple d film system was studied in the region of ferromagnetic resonance with lar ge amplitudes of the precession angle. The system exhibits manifestations c haracteristic of the nonlinear phenomena, including (i) a shift in the reso nance frequency with increasing microwave field strength and (ii) the exist ence of dynamic bistability regions with respect to the microwave frequency and the magnetizing field strength.
