X-ray spectroscopy study on the electronic structure of hole-doped edge-shared chains in Ca2+xY2−xCu5O10

X--ray absorption (XAS) and emission (XES) spectroscopy near O K edge has been performed on edge--shared CuO chain compounds Ca2+xY2--xCu5O10 (0*0*?x*?2*0) using poly-- and single--crystalline samples. Two large peaks are observed at 528*?eV (PH) and 530*?eV (PU) in the XAS spectra. The intensity of...
