Dielectric/piezoelectric resonance in high-strain Pb(Mg1/3Nb2/3)1-xTixO3 crystals.

This work presents dielectric resonance in Pb(Mg_1/3Nb_2/3)_1-xTi_xO₃ crystals after electric (E)-field poling, which is crucial for piezoelectric applications. Dielectric permittivity has been measured as functions of temperature, frequency, poling E-field strength, and Ti content (x=25% and 34%). Frequency-dependent dielectric spectroscopy after poling exhibits multiple piezoelectric resonances between 0.2 and 1 MHz, and can be described by the forced-damped-oscillator model. The resonant spectra show significant changes while phase transitions are taking place. [ABSTRACT FROM AUTHOR]
