摘要：
We consistently observe a magnetic-field-dependent conductance peak at zero-bias voltage in a wide range of superconductor/noble-metal junctions fabricated from oxide superconductors (YBa2Cu3O7-delta and Tl2Ba2CaCu2O) that have been reported to exhibit d-wave pairing behavior; however, no measurable peak appears in similar junctions made from an s-wave oxide superconductor (Nd1.85Ce0.15CuO4) Explanations of this correlation are considered in terms of the Appelbaum-Anderson model for magnetic interface scattering and the midgap-state model for d-wave interface states.
