Abstract

A new unified superspace approach to the structural characterization of two "compositionally flexible" compound series, La_nTi_n-δO_3n and Sr_n(Nb)_nO_3n+2, is presented. To a first approximation, the structure of any compound within either compound series can be described in terms of the stacking of layers derived from the ideal perovskite structure. A unique superspace model for each compound series is shown to predict the space group and layer stacking for any particular composition.
