## Description

- description: "We study the electronic structure of electron-doped Pr1.3−x La0.7
    Cex CuO4 (PLCCO; Tc = 27 K, x = 0.1) and hole-doped Bi2Sr2CaCu2O8+δ (Bi2212; Tc
    = 90K) cuprate superconductors using x-ray absorption spec- troscopy and resonant
    photoemission spectroscopy (Res-PES). From Res-PES across the O K-edge and Cu
    L-edge, we identify the O 2p and Cu 3d partial density of states (PDOS) and their
    correlation satellites, which originate in two-hole Auger final states. Using
    the Cini-Sawatzky method, analysis of the experimental O 2p PDOS shows an oxygen
    on-site Coulomb energy for PLCCO to be Up = 3.3 ± 0.5 eV, and for Bi2212, Up =
    5.6 ± 0.5 eV, while the copper on-site Coulomb correlation energy is Ud = 6.5
    ± 0.5 eV for Bi2212. The expression for the Heisenberg exchange interaction J
    in terms of the electronic parameters Ud, Up, charge-transfer energy \U0010FC00,
    and Cu-O hopping tpd obtained from a simple Cu2O cluster model is used to carry
    out an optimization analysis consistent with J known from scattering experiments.
    The analysis also provides the effective one-band on-site Coulomb correlation
    energy U ̃ and the effective hopping t ̃. PLCCO and Bi2212 are shown to exhibit
    very similar values of U ̃ /t ̃ ∼ 9–10, confirming the strongly correlated nature
    of the singlet ground state in the effective one-band model for both materials."
