Description

Experiments on x-ray photoelectron spectroscopy of Bi2Sr2Ca1-xYxCu2Oy were performed to investigate the change of valence of each atom and the distribution of Y atoms on the cation sites. The core-level binding energies of Sr and Y increased with increasing Y content and that of Bi did not change. The average valence of Cu was above 2 for 0.0≤x≤0.5 and below 2 for 0.8≤x≤1.0. Y atoms were substituted for the cations between the adjacent Cu-O planes
