Abstract
New nonthermal mechanism of sound photoexcitation in semiconductors having transition into ferromagnetic phase is proposed. The efficiency of this mechanism is compared with the efficiency of electron-deformation mechanism. Simple situation of a drift with constant velocity is described. The duration of generated acoustic pulse depends on the velocity of the drift and the thickness of transition area.
