title = "Structure of the high-Tc superconductor Ba2YCu3O7+x above (124 K) and below (71 K) Tc by neutron diffraction",
abstract = "The crystal structure of the high-Tc superconductor Ba2YCu3O7+x at 124 and 71 K was refined by Rietveld analysis of neutron-diffraction data. We found that at 124 and 71 K the structure is of the same space group Pmmm, but when the temperature is decreased and passes the critical temperature Tc, 0.12 of the oxygen population on the 1e site transfers to the 1b site. This remarkable change in the structure can be related to its superconductivity. {\textcopyright} 1987 The American Physical Society.",
