Abstract

Developing new techniques to design and discover novel superconductors, especially those with unusual symmetries of superconducting order parameters and/or exotic pairing mechanisms, opens new doors to future applications in quantum devices. The recent discovery of superconductivity in infinite-layer nickelates has engendered reviving interest in the study of a cuprate-analog system [1]. Notably, superconducting nickelates display signatures of intriguing similarities and distinctions to the cuprates in their phase diagrams, proximity to strongly correlated electronic phases [2], antiferromagnetic interactions [3], superconducting anisotropy [4], etc. Partially owing to the non-trivial challenges in materials synthesis and their thin-film nature [5], experimental demonstration of the intrinsic properties of this materials family has still been limited. In this talk, I will introduce this new family of superconductors synthesized by a soft-chemistry approach and highlight the key aspects of their electronic and magnetic structure. I will also present our latest developments in synthetic approaches to the nickelate materials system and probing of their distinct features, in a broader context of the unusual role that rare-earth elements and chemical environment play.<br/><br/>[1] D.
