摘要: Utilizing high-resolution O K-edge X-ray absorption spectra, we report a comparative study on the variation of hole states with Pr doping for Y-x Pr1-xBa2Cu3O7 and YxPr1-xBa2 Cu-4 O-8. The depletion rate of hole carriers in the CuO2 planes with Pr doping in YxPr1-xBa2Cu4 O-8 is considerably slower than that in YxPr1-xBa2Cu3O7. The oxygen content affects the depletion rate of hole carriers in cuprates with Pr doping. (C) 2004 Elsevier B.V. All rights reserved.
