摘要：

In situ transmission electron microscopy study of electric field-induced cracking has been conducted on [001] oriented 0.65Pb(Mg1/3Nb2/3)O-3-0.35PbTiO(3) crystal. Fracture of the 90 degrees domain boundary was directly observed in the tetragonal area under both static and alternating electric fields. The field strength required to induce domain boundary cracking was lower for alternating electric field than for static field. (C) 2000 American Institute of Physics. [S0003-6951(00)04636-2].
