Abstract
The 1/2{111}-type ordered structure observed in lanthanum-modified lea d zirconate titanate has been proved to be stable in the next-nearest- neighbor approximation by the eight-point cluster variation method. Th e order parameter as a function of the composition of La3+ and lead va cancies and the order-disorder phase diagram have been obtained.
