A complete set of polarised XAS spectra at Cu L3 and Bi L3- edges have been recorded on a well characterised single crystals of Bi2Sr2CaCu2O8+ superconductor. The Cu L3 spectra shows an energy difference of 400 meV between z(3d3z2-r2) and x,y(3dx2-y2) components, with a significant intensity in E parallel-to c polarisation. The Bi L3-edges show clearly the energy shift of superconductor spectra towards low energy with respect to Bi(III) references confirming again the Bi-O layers as electron reservoir.

Abstract

A complete set of polarised XAS spectra at Cu L3 and Bi L3- edges have been recorded on a well characterised single crystals of Bi2Sr2CaCu2O8+ superconductor. The Cu L3 spectra shows an energy difference of 400 meV between z(3d3z2-r2) and x,y(3dx2-y2) components, with a significant intensity in E parallel-to c polarisation. The Bi L3-edges show clearly the energy shift of superconductor spectra towards low energy with respect to Bi(III) references confirming again the Bi-O layers as electron reservoir.
