Abstract

Fatigue anisotropy in Pb(Zn 1/3Nb 2/3)O 3-PbTiO 3 ferroelectric single crystals with rhombohedral symmetry, was studied. The dependence of the switching behavior on the driving frequency and driving field strength was measured. Through measurement of strain-electric-field switching, an asymmetry in [111] C fatiguing crystals was observed. As the ferroelectric material fatigues, higher fields and slower cycling times were required to maximize the remanent polarization. Local changes in the amount of asymmetry and reversal in the asymmetry across the same crystal indicates that the internal field is the result of statistical events and not broken by symmetry from the first injection process.
