摘要

In this paper we presented the X-ray PDF investigation of orthorhombic Ba_2In_2O_5 and cubic Ba_2In _(1.7)P_(0.3)O_(5.3) and Ba_2In _(1.7)S_(0.3)O_(5.45) samples. Pure Ba _2In_2O_5 was found to be properly described-at the local scale-by the orthorhombic average structure. Ba_2In _(1.7)P_(0.3)O_(5.3) and Ba_2In _(1.7)S_(0.3)O_(5.45) cannot be described, at the local scale, by a cubic symmetry. The PDFs of these two samples clearly showed a distorted atom arrangement in the short-range which can be described again with the orthorhombic symmetry found in pure barium indate. This journal is
