The relationship between the intensity of shock magnetoelastic oscillations of the magnetization and the time-varying properties of iron borate has been studied for the first time. When the main stage of the magnetization reversal lasts < 13-16 ns, there is a sharp decrease in the efficiency of the energy transfer from the magnon system of the crystal to the phonon system. As a result, there is a sharp increase in the rate of magnetization reversal. A change in slope occurs on the curve of the pulsed magnetization reversal.
