Synthesis and Development of new Kagome Metal Motifs

ORAL  · Invited

Abstract

Continued efforts into understanding complex electronic and magnetic states in kagome metals has served as a great impetus for the discovery of new kagome metals. This is particularly the case for low-dimensional crystal structures (e.g. our prior discovery of the AV3Sb5 kagome superconductors and recent discoveries in the AM3X4 kagome magnets, both of which are exfoliable). In this chemistry-focused talk, we present our experimental methodology for discovering new kagome metals alongside a discussion of several new families of compounds. Examples include; our ability to tune magnetism in a new series of AM3X4 layered magnets, a new density-wave transition in a nonmagnetic kagome metal, a new kagome prototype built from the AM3X5 structural motif, and new frontiers in the larger AM6X6 kagome family. Our results provide the community with new single-crystal platforms for the exploration of magnetic, structural, and electronic instabilities in kagome metals.
