Аннотация
Excitation of ferroelectric-magnetic oscillations in ferroelectric-magnetic materials by a nonrelativistic electron beam is analyzed in the electrostatic and the magnetostatic approximations. The amplification increments of spin and ferroelectric waves are calculated. It is shown that an electron beam can be an effective means of wave excitation in a ferroelectric-magnetic crystal.
