This work presents dielectricresonance in Pb(Mg1∕3Nb2∕3)1−xTixO3 crystals after electric (E)-field poling, which is crucial for piezoelectric applications. Dielectricpermittivity 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 piezoelectricresonances between 0.2 and 1MHz, and can be described by the forced-damped-oscillator model. The resonantspectra show significant changes while phase transitions are taking place.
