What is Structural anomalies and non-linearity of Cu-O chains in YBa2Cu3O7 by high resolution neutron powder diffraction about?
The structure of orthorhombic YBa2Cu30 x was redetermined on two very pure samples with xi~6.86 and x2~6.91, in the temperature interval 5-320K using high resolution neutron diffraction. No major structural change is observed at the onset of superconductivity but the lattice dimensions and some of the structural parameters show small anomalies at or near 90K and 240K. All vibrational amplitudes are normal except for those of the 04 atoms across the Cu-O chain, which are large. Good agreement with the data is obtained by assuming that the 04 atoms occupy potential minima at about 0.1A away from either side of the chain axis.
