摘要: Abstract The nonlinear dielectric responses of both unpoled and poled Mn-doped PMS-PZT ceramics as a function hydrostatic pressure were investigated. Based on the application Rayleigh law analysis, contribution irreversible domain wall motion to response under was quantitatively evaluated. Initial increased extrinsic observed in samples which can be ascribed induced pinning relaxation effect. In addition, depolarization effect may also facilitate related samples. present study shed further light understanding dynamic piezoelectric is quite helpful for design optimization devices used underwater areas.
