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. 000894200 536__ $$0G:(DE-HGF)POF4-632$$a632 - Materials – Quantum, Complex and Functional Materials (POF4-632)$$cPOF4-632$$fPOF IV$$x0 000894200 536__ $$0G:(DE-HGF)POF4-6G4$$a6G4 - Jülich Centre for Neutron Research (JCNS) (FZJ) (POF4-6G4)$$cPOF4-6G4$$fPOF IV$$x1 000894200 588__ $$aDataset connected to DataCite 000894200 7001_ $$0P:(DE-Juel1)178022$$aJana, S.$$b1 000894200 7001_ $$0P:(DE-Juel1)177779$$aNandi, Shibabrata$$b2$$ufzj 000894200 7001_ $$0P:(DE-HGF)0$$aStunault, A.$$b3 000894200 7001_ $$0P:(DE-Juel1)130884$$aPerßon, J.$$b4 000894200 7001_ $$0P:(DE-Juel1)130572$$aBrückel, T.$$b5 000894200 8564_ $$uhttps://juser.fz-juelich.de/record/894200/files/Program%20Booklet%20PNCMI%202021_Rai.pdf$$yRestricted 000894200 909CO $$ooai:juser.fz-juelich.de:894200$$pVDB 000894200 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)178021$$aForschungszentrum Jülich$$b0$$kFZJ 000894200 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)178022$$aForschungszentrum Jülich$$b1$$kFZJ 000894200 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)177779$$aForschungszentrum Jülich$$b2$$kFZJ 000894200 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130884$$aForschungszentrum Jülich$$b4$$kFZJ 000894200 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130572$$aForschungszentrum Jülich$$b5$$kFZJ 000894200 9131_ $$0G:(DE-HGF)POF4-632$$1G:(DE-HGF)POF4-630$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lFrom Matter to Materials and Life$$vMaterials – Quantum, Complex and Functional Materials$$x0 000894200 9131_ $$0G:(DE-HGF)POF4-6G4$$1G:(DE-HGF)POF4-6G0$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lGroßgeräte: Materie$$vJülich Centre for Neutron Research (JCNS) (FZJ)$$x1 000894200 9141_ $$y2021 000894200 9201_ $$0I:(DE-Juel1)JCNS-2-20110106$$kJCNS-2$$lStreumethoden$$x0 000894200 9201_ $$0I:(DE-Juel1)PGI-4-20110106$$kPGI-4$$lStreumethoden$$x1 000894200 9201_ $$0I:(DE-82)080009_20140620$$kJARA-FIT$$lJARA-FIT$$x2 000894200 980__ $$aabstract 000894200 980__ $$aVDB 000894200 980__ $$aI:(DE-Juel1)JCNS-2-20110106 000894200 980__ $$aI:(DE-Juel1)PGI-4-20110106 000894200 980__ $$aI:(DE-82)080009_20140620 000894200 980__ $$aUNRESTRICTED 000894200 981__ $$aI:(DE-Juel1)JCNS-2-20110106
