A rf magnetic field applied to the high-Tc superconductor YBa2Cu3O7 under a crossed dc magnetic field generates a transverse ultrasonic wave, associated with the tilt of pinned vortices. The reverse situation, in which the rf field is generated by the application of the ultrasonic wave, also exists. The polarization of the transverse ultrasonic wave is parallel to the rf field. Experimental results related to line and Josephson vortices are presented as functions of temperature and magnetic fields.
