Description
This paper discusses atomic pair distribution analysis of pulsed neutron scattering data for superconducting oxides which indicates that some of the atoms, notably oxygen atoms, are displaced from the crystallographic high-symmetry sites, breaking the local symmetry. Anomalous displacements are seen in Tl-Ba-Ca-Cu-O in the vicinity of the superconducting transition temperature, suggesting an unusual nature of the superconducting state of this compound
