Recent theoretical predictions and experimental realizations of exotic fermions and topologically protected phases in condensed matter have led to tremendous research interests in topological quantum materials. Especially, correlated topological materials, such as magnetic Dirac and Weyl semimetals, and intrinsic magnetic topological insulators etc., in which both non-trivial topology of single-electron band structures and electronic correlation effects are essential for the underlying physics, have emerged as an exciting platform to explore novel electronic and magnetic phenomena. In this talk, I will present a couple of the selected examples of our recent neutron scattering studies of correlated topological materials, including magnetic Dirac semimetal EuMnBi$_2$ [1], magnetic Weyl semimetal Mn$_3$Sn and topological magnon insulators in two-dimensional van der Waals ferromagnets CrSiTe$_3$ and CrGeTe$_3$ [2].
