      abstract     = {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. Zhu, X. Wang, Y.
