AB  - Magnetic topological quantum materials, such as magnetic Dirac and Weyl semimetals, andintrinsic magnetic topological insulators, in which topologically non-trivial band structures,magnetism and electronic correlation effects can be intertwined, have recently emerged as anexciting platform to explore exotic states and novel functionalities. As a unique microscopicprobe for magnetism, neutron scattering is ideally suited for the investigations of magneticcorrelations over a wide range of length and time scales in these novel quantum materials. Inthis talk, I will present some highlights from our recent neutron scattering studies of emergentphenomena in magnetic topological quantum materials [1-4], including the realization of exotictopological magnon insulators in the two-dimensional van der Waals ferromagnets CrSiTe$_3$ andCrGeTe$_3$ [2], and the observation of flat-band engineered spin-density wave in the magneticWeyl semimetal Mn$_3$Sn [3], as well as the discovery of emergent topological Hall effect in themagnetic kagome metal RMn$_6$Sn$_6$ [4].We thank F.
