Abstract
X-ray absorption spectra at the oxygen K edge using the total yield technique are reported for YBa2Cu3O6.9 and YBa2Cu2.7Fe0.3O6.9. A comparison of the two spectra reveals that the mobile holes in YBa2Cu3O7−δ are removed and localized on Fe doping. Fe thus enters the lattice primarily in the formally trivalent oxidation state.
