Transport properties of superconducting bilayer nickelate thin films

Bilayer nickelates have emerged as a new class of high-temperature superconductors, featuring a cuprate-like crystal structure but a distinct d^7.5 electronic configuration. While bulk crystals require high-pressure conditions to stabilize superconductivity, epitaxial thin films under compressive strain have enabled superconductivity at ambient pressure. This advance allows direct comparison between the high-pressure and strain-stabilized counterparts, offering complementary insights into the origin of superconductivity. It also opens up a broader experimental access to superconductivity and its neighboring phases. In this talk, we present recent progress on superconducting bilayer nickelate thin films, with a focus on transport properties that can be effectively tuned through strain and soft chemistry methods. We highlight how such tunability offers new perspectives on the nature of superconductivity in bilayer nickelates.
