Flat bands near the Fermi level in a topological kagome magnet revealed using angle-resolved photoemission spectroscopy

ORAL

Abstract

Kagome magnets have attracted significant attention as they are known to host exotic magnetic orders and strongly correlated quantum phases. In this study, we examine the electronic structure of the family of topological magnets based on a distorted kagome lattice. Our data points to the presence of flat bands at or in a very close proximity to the chemical potential, which makes these materials an ideal playground for exploring the relationship between flat bands, strong correlations, and magnetism.
