Title: Scaling behavior of YBa 2 Cu 3 O 7 delta thin-film weak links
Published: July 06, 1990
Abstract: The superconductive weak link properties of microbridges formed in c-axis normal YBa 2 Cu 3 O 7 δ polycrystalline thin films containing a variable amount of large angle tilt boundaries have been studied. In the low critical current density limit these weak links have current-voltage (I-V) characteristics that are accurately modeled by the resistively shunted junction model. The I-V's are found to accurately follow a simple scaling law with the product of the critical current and weak link resistance Rn varying linearly with the weak link conductance.
