Abstract

We present the results of Cu and Y K-edge and rare-earth and Ba L-edge x-ray absorption measurements on a series of new quaternary high-Tc superconducting compounds La2-xSrxCuO4-y and RBa2Cu3O7 (R=Y,Er,andHo). The Cu K-edge results are shown to reflect the Cu valence state in these materials. The other measurements are discussed in the context of binary rare-earth oxides and the quantitative influence of bond lengths on continuum resonances in such spectra.
