The temperature and field dependences of the conversion efficiency of electromagnetic and ultrasonic waves in Gd single crystals are studied. The longitudinal ultrasound excitation peak is detected at the paramagnet-ferromagnet phase transition. The conversion efficiency changes dramatically during the spin-flip transitions.
