摘要: Domain switching behavior of 0.955 Pb (Zn 1/3 Nb 2/3) O 3–0.045 PbTiO 3 ferroelectric single crystal has been investigated using the ultrasonic technique in addition to the polarization hysteresis measurements. The ultrasonic technique makes it possible to extend the coercive field measurement to frequencies as low as 10− 5 Hz, revealing the existence of a saturated coercive field E sc, which representing the intrinsic switching barrier.
