Abstract
Excitation of the spin waves in ferroelectric-ferromagnet by oscillations of ferroelectric domain wall as a whole in alternating electric field was investigated in the frame of oscillatory model. It was shown that due to the fact that frequency of ferroelectric domain wall oscillations as a whole lies in spin wave region the resonance excitation of spin waves is possible. That means that the amplitude of generated spin waves has resonance type dependence on spin wave frequency. This paper also deals with investigation of excitation of electric polarization in ferromagnet and in ferroelectric-ferromagnet by oscillations of magnetic domain wall as a whole in alternating magnetic field. It was shown that electric polarization excitations are localized on magnetic domain wall.
