Oxidation states of Cu, Ba and Y in superconducting YBa2Cu3O7−x

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

A high temperature (91.2 K) Y−Ba−Cu−O superconductor has been studied by monochromatized XPS core level measurements. The position, shape and satellite emission of Cu 2p indicate a mixture of Cu valencies 2+ and 1+ with some indication for the existence of a third oxidation state of 3+. The two component structure of the Ba 3d line suggests two principal Ba−O configurations due to oxygen vacancies. The shape and position of the Y 3d doublet imply only weak Y−O interactions.
