| 英文摘要 | The two-dimensional bi2sr2cacu2o8+y (bi2212), the most studied prototype cuprate superconductor, is a lamellar system made of a stack of two-dimensional corrugated cuo2 bilayers separated by bi2o2 + y sr-2 o-2 layers. while the large majority of theories, proposed to interpret unconventional high t (c) superconductivity in bi2sr2cacu2o8+y , assume a centrosymmetric tetragonal cuo2 lattice for the [cuo2]ca[cuo2] bilayer, here, we report new compelling results providing evidence for local noncentrosymmetric symmetry at the cu atom. we have measured polarized cu k-edge xanes (x-ray absorption near-edge structure) and the k-edge x-ray magnetic circular dichroism (xmcd) of a bi2212 single-crystal near-optimum doping. the cu k-edge xmcd signal was measured at id12 beamline of esrf with the k-vector of x-ray beam parallel to c-axis, i.e., with the electric field of x-ray beam e//ab, using a 17-t magnetic field parallel to the c-axis of a bi2212 single crystal. numerical simulations of the xmcd signal of bi2212 by multiple scattering theory have shown agreement with the experimental xmcd signal only for the local structure with noncentrosymmetric bb2b space group of bi2sr2cacu2o8+y . |
