The polarized copper K-edge x-ray absorption near edge structure (XANES) of YBa2Cu3O7 has been calculated by using the full multiple scattering approach. The Cu K-edge EXAFS of YBa2Cu3O≈7 as a function of temperature is also analyzed. From this analysis we obtain evidence for a slight structural modification at Tc which can be associated with the superconductive transition.

Abstract
The polarized copper K-edge x-ray absorption near edge structure (XANES) of YBa2Cu3O7 has been calculated by using the full multiple scattering approach. The Cu K-edge EXAFS of YBa2Cu3O≈7 as a function of temperature is also analyzed. From this analysis we obtain evidence for a slight structural modification at Tc which can be associated with the superconductive transition.File in questo prodotto:
