Superconducting half-dome in bilayer nickelates

Understanding how superconductivity emerges and collapses in correlated electron systems remains a central challenge in condensed matter physics. As a recently discovered member of the high temperature superconductor family, bilayer nickelates provide a new opportunity for examin...

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...
