Abstract

Interatomic distances and distributions of rare-earth and strontium cations over two sites in the structure of (La1−x Hox)2SrAl2O7 solid solutions were determined by means of full-profile X-ray structural analysis. Introduction of holmium cations into the La2SrAl2O7 oxide results in ordered distribution of Ln3+ cations and stabilization of the perovskite-like structure.
