SYMPOSIUM 25 – Nickelates: Superconductivity, Correlations, and Emergent Phenomena

This symposium focuses on recent advances in nickelates, with emphasis on synthesis, structure–property relationships, magnetism, and the roles of strain, dimensionality, and oxygen nonstoichiometry in superconductivity and other emergent correlated phases. As complex oxide ceramics with strongly coupled electronic, magnetic, and structural degrees of freedom, nickelates lie at the intersection of superconductivity, functional ceramics, and perovskite oxide science.

The recent discovery of ambient-pressure superconductivity in nickelate at temperatures comparable to other high-temperature superconductors has generated significant excitement and established nickelates as a rapidly emerging platform for exploring strongly correlated phenomena. This symposium aims to provide a forum for researchers working on bulk and thin-film synthesis, post-growth reduction treatments, defect and interface engineering, advanced structural, spectroscopic, and electronic characterization, and theoretical modeling of nickelates. By bringing together the condensed matter physics, materials science, ceramics, and theory communities, the symposium will foster interdisciplinary collaborations that leverage expertise in oxide synthesis, processing, characterization, and computational and theoretical approaches to accelerate the discovery and understanding of emergent phenomena in nickelate materials.
