      abstract     = {Topological quantum materials have attracted enormous
                      attention since their discovery due to the observed
                      anomalous transport properties, which originate from the
                      non-zero Berry curvature. Mn3+δGe has gained special
                      attention because of its large anomalous transport effects
                      that persist starting from Néel temperature (365 K) down to
                      2 K. Hexagonal - Mn3+δGe stabilizes in the range of δ =
                      0.25 to 0.55. We have observed larger anomalous Hall effect
                      with very small hysteresis (<200 Oe) for high Mn
                      concentration in Mn3+δGe. To establish the claim for the
                      existence of Weyl points in Mn3+δGe, transverse and
                      longitudinal magneto-resistance (MR) was also performed with
                      field and current applied along several combinations of x,
                      y, z crystallographic axes. Negative MR is observed in some
                      cases even when magnetic field (B) is perpendicular to the
                      current (I) direction. However, in case of I∥B∥x,
                      negative MR is observed with different slopes below and
                      above 2 T. Angle dependent measurement (between I and B)
                      shows that the negative MR with higher slope (observed below
                      2 T) is possibly originating due to the chiral anomaly.},
