Superconducting Weak Links at Substrate Steps in Bilayer Nickelate Films

Abstract Ambient-pressure superconductivity above 40 K has been realized in bilayer nickelate thin films on SrLaAlO4 (001), yet resistive measurements often exhibit incomplete zero-resistance states and/or two-step superconducting transitions of unresolved origin. We show that th...
