Stripe structure of the CuO2 plane in Bi2Sr2CaCu2O8+y by anomalous x-ray diffraction.

Abstract:

The modulated structure of the CuO2 plane in Bi2Sr2CaCu2O8+y superconductor has been solved by Cu K-edge anomalous x-ray diffraction. The displacement of Cu ions along the c axis shows the largest amplitude and enharmonic character. The results show flat stripes of CuO2 lattice of width L = 15.5 Å with long Cu-Bi distances that are separated by stripes of bent CuO2 plane and shorter Cu-Bi distances. In each CuO2 bilayer the flat stripes in a first layer are close to the bent stripes in the se...
