Abstract

Neutron powder diffraction has been used to study the oxygen defect chemistry of two non-superconducting layered cuprates, La_1.25Dy_0.75CuO_3.75F_0.5, having a T*-related structure, and La_1.85Sr_1.15Cu₂O_6.25, having a structure related to the that of the newly discovered double-layer superconductor La_2-xSr_xCaCu₂O₆. The role played by oxygen defects in determining the superconducting properties of layered cuprates is discussed.
