Abstract

We have performed an angle-resolved photoemission study on untwinned PrBa₂Cu₃O₇, which has low resistivity but does not show superconductivity. We have observed a dispersive feature with a band maximum around (π/2,π/2), indicating that this band is derived from the undoped CuO₂ plane. We have observed another dispersive band exhibiting one-dimensional character, which we attribute to signals from the doped CuO₃ chain. The overall band dispersion of the one-dimensional band agrees with the prediction of the t-J model calculation with parameters relevant to cuprates except that the intensity near the Fermi level is considerably suppressed in the experiment.
