• Heating by less than 10℃ of heavy water was observed at room temperature upon the propagation of acoustic waves of 6 MHz with intensity of about 2W/cm^2 during the scanning of a magnetic field from 800 to 1000mT. A control experiment with light water did not show the heating. As a quantitative explanation of this heating, the "spin-flip phonon maser" action of deuterons due to the thermal Raman process of spin-phonon coupling is considered. Good agreement with the experimental result was obtained. The 6 MHz acoustic waves induce the pumping transitions of the nuclear spin system.
