001047233 520__ $$aTopological quantum materials have attracted enormous attention since their discovery due to theobserved anomalous transport properties, which originate from the non-zero Berry curvature. Mn3Xcompounds show interesting physical properties like Anomalous Hall Effect (AHE), Planar Hall effect(PHE), chiral magnetic effect, and non-local transport properties due to non-vanishing Berryflux emerging from the Weyl points [1]. It is widely believed that the magnetic structure and Weylproperties are intimately connected.Nevertheless, the interpretation of negative longitudinal magnetoresistance (LMR), AHE, and PHEin Mn₃X compounds—particularly their connection to the chiral magnetic effect—remains a subjectof ongoing debate. This presentation provides a concise overview of current insights into these phenomena,with a focus on experimental observations in Mn₃Sn and Mn₃Ge using neutron diffractionand complementary physical property measurement systems.References:[1] S.
