Design and fabrication of PIN-PMN-PT single-crystal high-frequency ultrasound transducers

IEEE Trans Ultrason Ferroelectr Freq Control. 2009 Dec;56(12):2760-3. doi: 10.1109/TUFFC.2009.1367.

Abstract

High-frequency PIN-PMN-PT single crystal ultrasound transducers at center frequencies of 35 MHz and 60 MHz were successfully fabricated using lead indium niobate-lead magnesium niobate-lead titanate (0.23PIN- 0.5PMN-0.27PT) single crystal. The new PIN-PMN-PT single crystal has higher coercivity (6.0 kV/cm) and higher Curie temperature (160 degrees C) than PMN-PT crystal. Experimental results showed that the PIN-PMN-PT transducers have similar performance but better thermal stability compared with the PMN-PT transducers.
