Abstract

Rietveld analysis of X-ray powder diffraction data was performed on SmBa4Cu3O8.5+δ, which was synthesized from precursors Sm2O3, BaO2, and CuO at 1000 °C in an oxygen atmosphere. SmBa4Cu3O8.5+δ has a cubic perovskite-related structure that is isostructural with YBa4Cu3O8.5+δ, and a doubled perovskite unit cell parameter of 8.177 90±0.000 04 Å.
