The article presents solutions to a system of dynamic equations describing the influence of magnetic waves on the generation of longitudinal acoustic waves during domain boundary motion in yttrium orthoferrite, taking into account the external constant magnetic field and absorption. It is established that the increase in the influence of the magnetic subsystem on the generation of a longitudinal acoustic wave depends on the velocity of the domain boundary. The calculations show that the greatest contribution of the magnetic wave to the generation of a longitudinal acoustic wave during domain boundary motion at a velocity of about 106 cm/s is about 10-12 cm.
Keywords:domain boundary; magnetic waves; longitudinal acoustic waves; transverse acoustic waves; yttrium orthoferrite; slowly changing amplitudes
