Domain structures arising as a result of pulsed electric fields are investigated in Pb(Zn1/3Nb2/3)O3-PbTiO3 (PZN-PT) 〈001〉 single crystals by means of etching and environmental scanning electron microscope. It is shown that randomly orientated dendritic domain patterns were created under a pulsed electric field condition. The dendritic patterns are believed to be the result of local electric field and elastic deformation. Dendritic structures are also found during a back-switching process in 0.92PZN-0.08PT  single crystals. It is hypothesized that these unusual nonequilibrium domain structures are the result of local defects and space charge in the relaxor PZN-PT crystals.
