    • Abstract

       

      Stress dependence of domains in thick crystals of PbNb2O6 is reported. Successive etching shows numerous domains in the bulk not extending to the surface. These domains have correlation with the dislocation substructure in the bulk. The dislocations are in the form of small loops, and domain walls are found terminating along with these loops. The general problem of volume nucleation is discussed, and it is suggested that these dislocation loops play a significant role in domain formation.
