Abstract
The dynamical conversion of magnetogyrotropic waveguide modes in the regime of uniform spin precession at large angles is studied. It is shown that the nutation of the magnetization vector due to the precession frequency doubling results in dependence of the light modulation amplitude on the polarization of the microwave field. The contribution of harmonics with frequencies that are multiples of the fundamental precession frequency of ferromagnetic resonance to the total mode-conversion efficiency is analyzed for different lengths of the waveguide and different equilibrium orientations of the magnetization.
