| 520 | _ | _ | |a Topological quantum materials have attracted enormous attention since their discovery due to the observed anomalous transport effects (ATE), which originate from the non-zero Berry curvature. Mn3Ge has gained special attention because anomalous transport effects can be studied below the Néel temperature (365 K), down to 2 K [1]. Since ATE emerge from the robust topological band structure, it is interesting to study the effects of Fe doping on ATE in (Mn1-xFex)3Ge. Our transport measurements show the existence of an anomalous Hall effect (AHE) in the intermediate temperature range for the 22% Fe doped sample. However, the origin of the AHE cannot be attributed to Weyl points without knowledge of the ground state magnetic structure of doped samples. Therefore, we have performed polarized neutron diffraction from the (Mn0.78Fe0.22)3Ge sample using the D3 CRYOPAD setup at ILL, France. Our analysis concludes that the magnetic structure of the 22% Fe doped sample remains the same as Mn3Ge in the temperature range where AHE is observed. This suggests that the physics behind AHE observed in doped samples is most likely the same as in Mn3Ge. Therefore, it can be argued that the Weyl Fermions do not vanish by suitable doping of the sample, as long as the magnetic structure of the doped samples remains the same. |
