Abstract

A focused mini colloquia on superconducting nickelates is timely given the rapid pace of discoveries. Recent breakthroughs in Sm-based infinite-layer nickelates, showing superconductivity near 40 K, have reinvigorated the search for cuprate analogs and expanded the landscape of high-temperature superconductivity. These materials not only challenge existing theoretical frameworks but also call for new experimental approaches to probe their unconventional pairing mechanisms. Equally significant are reports of superconductivity in bilayer nickelates with Tc approaching 90 K under pressure, and 40–60 K with compressive strain at ambient pressure. 

Such results underscore the powerful role of structural engineering, extreme conditions, and epitaxial strain in enhancing superconductivity, pointing toward rational design strategies for nickelates at ambient pressure. Gathering experts in thin film growth, spectroscopy, and theory within a small symposium at the CMD conference would enable focused discussion on how layering and strain reshape electronic structures and elevate Tc. This Colloquium would also help shape the European research agenda at a pivotal stage, consolidating diverse results into a coherent framework. By concentrating on Sm-based infinite-layer and strain-engineered bilayer nickelates, the meeting could define scientific challenges, attract new researchers, and accelerate progress toward higher-temperature superconductors.
