    摘要

    The variation of hole states with Pr doping for Y x Pr 1-x Ba 2 Cu 3 O 7 and Y x Pr 1-x Ba 2 Cu 4 O 8 has been investigated by O K-edge X-ray absorption spectroscopy. Upon Pr substitution, T c suppression rate in Y x Pr 1-x Ba 2 Cu 4 O 8 is slower than that in Y x Pr 1-x Ba 2 Cu 3 O 7 . For both systems, hole carriers in the CuO 2 planes and CuO chains decrease monotonically with increasing Pr doping level. The depletion rate of hole carriers in the CuO 2 planes with Pr doping in Y x Pr 1-x Ba 2 Cu 4 O 8 is considerably slower than that in Y x Pr 1-x Ba 2 Cu 3 O 7 . The oxygen content affects the depletion rate of hole carriers in cuprates with Pr doping.
