Nonresonance interaction of acoustic and magnetoplasma waves in a compensated metal
Abstract
The nonresonance coupling of ultrasound with a weakly attenuating magnetohydrodynamic wave in the electron-hole compensated-metal plasma is investigated theoretically. It is shown that the interaction of this kind generates an additional wave of mechanical displacements propagating at a supersonic velocity. The relative amplitude of the additional wave is calculated as a function of the intensity of the applied magnetic field for both contact and electromagnetic sound excitation.
