Abstract

The O-1s and Cu-2p_3/2 X-ray absorption near-edge spectra of YBa_2-xLa_xCu₃O_y have been measured by using synchrotron radiation. The total number of holes, as derived from the spectral data, decreases linearly with the increase of La content, x. The holes of O(4) are altered slightly, as compared to the decrease in the holes of the CuO₂ planes, by the La³⁺ substitution of Ba²⁺. The main effect of La in YBa_2-xLa_xCu₃O_y is to change the electronic structure in the CuO₂ planes so that the concentration of the hole states is reduced.
