Abstract

Phenomena resembling a tunneling behavior have been observed on dc sputtered Nd1+xBa2-xu3Oy c-axis oriented films. The current voltage characteristics at 4.2K give evidence of quasiparticle tunneling current as usually measured in superconductor-insulator-normal metal or superconductor-insulator-superconductor junctions, with normal resistance values of about 10Ω. In the conductance curves, peak at about +/-16mV are clearly visible. An analysis of these features is presented up to temperatures close to the sample critical temperature.
