| 520 | _ | _ | |a Weyl semimetal (WS) - Mn3Ge displays a large anomalous Hall effect (AHE), which originates from the non-zero Berry curvature. The location and separation of the Weyl nodes can be tuned using a suitable dopant. So, we have studied the evolution of transport properties of single-crystal (Mn1−αFeα)3Ge. We observed that the strength of AHE and chiral anomaly weakens drastically with an increase in Fe doping and vanishes beyond α = 0.22. Polarized and unpolarized neutron diffraction of α = 0.22 showed that the magnetic structure of the compound remains the same as that of the parent compound, only in the temperature regime where AHE and the chiral anomaly are observed. These observations suggest the location of Weyl points and separation between a pair of Weyl points change significantly with Fe doping. Therefore, suitable dopants can be used to tune the transport properties of the WS. |
