摘要
Unoccupied electronic states of Y1-xPrxBa2Cu3O7-y (x = 0 - 1) thin films have been investigated using high-resolution polarization-dependent O K-edge x-ray absorption spectroscopy (XANES). After determining the hole distribution among different oxygen sites of the Pr-doped thin films, we compare the experimental data with the Fehrenbacher and Rice (FR) model and the Liechtenstein and Mazin (LM) model, both of which are based on the hybridization of Pr 4f=(x2-y2) and O 2pπ orbitals in PrBa2Cu3O7-y Our experimental results are more consistent with the FR model.
