Abstract

We report a study of X-ray absorption near-edge structure of the O K and Cu L₃ edges in YBa₂Cu_3-xFe_xO_7+y for x=0.01, 0.05 and 0.15. We attribute the peaks below 529 eV in the O K edge spectra of YBa₂Cu_3-xFe_xO_7+y to holes on the O sites. Our results show hole filling with increasing Fe content, which means that Fe enters the structure primarily in the formally trivalent oxidation state. Cu L₃ edge spectra reveal increased amounts of Cu³⁺ with increasing Fe content. The results are discussed in terms of charge balancing.
