Abstract

The aging effect of a 0.2 mol % Fe-doped 0.62Pb (Mg13 Nb23) O3 -0.38PbTi O3 single crystal was investigated. The authors found that aging induced a double ferroelectric hysteresis loop and a giant recoverable electrostrain of 0.8% at an electric field of 1.2 kVmm in the 〈001〉-oriented tetragonal crystal. This result is much higher than the strains obtained in crystals near the morphotropic phase boundary under the same field. Such aging effect is attributed to a point-defect-mediated reversible domain-switching mechanism. Large electrostrains (>0.55%) at 1.2 kVmm for a broad temperature from room temperature to 160 °C suggest that the aged single crystal is a promising electromechanical material.
