Abstract: Following the discovery of a quantum-limit magnetic Chern phase in TbMn6Sn6 and the observations of a large topological Hall effect (THE) in the various field-induced magnetic phases in YMn6Sn6 etc., the magnetic topological metals RMn6Sn6 (R = rare earth), that possess a bilayer kagome lattice of Mn, have recently emerged as a new platform to explore exotic quantum states that arise from the interplay between magnetism and non-trivial topological states in both k-space and real space. Understanding and eventual manipulation of these exotic quantum states can lead to potential technological applications in spintronics and quantum technologies. In this talk, I will mainly present our recent neutron scattering studies of static and dynamic magnetism in several representative magnetic topological metals RMn6Sn6, with the focus on possible temperature, magnetic-field, pressure and rare-earth tuning of their complex magnetism over a vastly different length scales, between colinear magnetic order, various zero-field and field-induced incommensurate spiral orders and possible non-coplanar spin textures. We have also observed a large THE that is directly associated with the field-induced non-coplanar incommensurate magnetic phase in these compounds. Our study has thus hinted a fascinating interplay between highly tunable magnetism and topologically non-trivial states in these bilayer kagome metals via intrinsic engineering of Berry curvature in both k-space and real space.
