摘要

The recent research work on domain structures and their dynamics in fenoelastic and ferroelectric crystals by white-beam synchrotron radiation topography is summarized.The real-time imaging,fine-beam Laue diffraction,and anomalous-scattering topography were carried out to the study of the domain structures and phase transition in the ferroelastic NdP5O14 and LaP5O14,and ferroelectric KTa1-xNbxO3,(Ba0.25Sr0.75)0.9(K0.5Na0.5)0.2Nb2O6,and KTiOPO4 crystals.Some preliminary results are presented and discussed.
