摘要：

Direct reciprocal conversion of sound and rf electric field E normal to the a-b plane has been realized in a single crystal YBCO in the absence of external magnetic field. Experiment was carried out at frequency 200 MHz. We have discovered that ultrasonic pulses generation was registrated in the range 5 K -130 K upon heating. The results are discussed within the model of ferroelectric phase transition which causes the development of the piezoeffect behaviour.
