000890925 520__ $$aTopological quantum materials have attracted enormous attention since their discovery due to the observedanomalous transport properties, which originate from the non-zero Berry curvature. Mn3X compounds showinteresting physical properties like Anomalous Hall Effect (AHE), Planer Hall effect (PHE), chiral magneticeffect, and non-local transport properties due to non-vanishing berry flux emerging from the Weyl points1.It is widely believed that the magnetic structure and Weyl properties are intimately connected.However, the observation of negative longitudinal magnetoresistance (LMR), AHE and PHE in Mn3Xcompounds and it’s connection with the chiral magnetic effect is much debated in the literature. In this talk,I will give a brief overview of the current understanding of the negative LMR, AHE and PHE as observed inMn3Sn and Mn3Ge compounds.References:[1] S. Nakatsuji, N. Kiyohara and T.
