High-Power Characterization of d32-Mode Mn:PIN-PMN-PT Piezoelectric Single Crystals at Different Temperatures

Mn:PIN-PMN-PT plates: [011]-poled (mm2 symmetry, d
32
-mode) were characterized at high-power excitation levels and at different temperatures. A bespoke high-power measurement system was utilized to acquire the electrical impedance at resonance. Results have shown that the resonant frequency/anti-resonant frequency downshifts with increasing driving voltage and temperature.
