Abstract
The atomic structure of ordered domains in Ba(Mg1/3Nb2/3)O-3 and La-do ped and undoped Pb(Mg1/3Nb2/3)O-3 is Studied by high-resolution Z-cont rast imaging. The ordered domain structure in both doped and undoped P b(Mg1/3Nb2/3)O-3 is determined to be in agreement with the charge bala nced random-layer model and inconsistent with the space-charge model. It is shown that La doping in Pb(Mg1/3Nb2/3)O-3 enhances not only the domain size but also the degree of ordering. (C) 1998 American Institu te of Physics.
