Abstract

In this article, we investigate the domain switching near crack tips in 0.62Pb(Mg_1/3Nb_2/3)O₃ -0.38PbTiO₃ (PMNT62/38) single crystal poled along the [001] orientation by polarized-light microscopy. The experimental results reveal that cyclic electric fields stimulate cyclic domain switching near a crack tip. Though the applied electric field is far lower than the coercive electric field, the intensive electric field is able to induce domain switching at a crack tip. Such switched domains are reversible after removal of the applied field.
