      abstract     = {A large Anomalous Hall Effect (AHE) has been found in Mn3Sn
                      due to the non-vanishing Berry flux emerging from the Weyl
                      points. This compound draws enormous interest due to the
                      complicated magnetic structure and its correlation with the
                      transport properties. We observed AHE from 420 K (TN = 420
                      K) down to 5 K for Mn3.17Sn. From single-crystal neutron
                      diffraction, we conclude that the magnetic structure is
                      commensurate with magnetic moments in the hexagonal basal
                      plane between 420 K (TN) < T < 5 K. An additional
                      incommensurate phase appears below 250 K. The presence of
                      AHE in the whole temperature range is consistent with the
                      commensurate magnetic structure. Fe doping influences the
                      nearest-neighbor exchange energy, thereby changing the
                      magnetic and transport properties. The Néel temperature was
                      found to be 405 K for Mn3.02Fe0.08Sn, slightly lower than
                      the parent compound. The commensurate magnetic structure has
                      been observed between 210 K < T < 405 K from neutron powder
                      diffraction. An incommensurate magnetic phase was observed
                      below 210 K. The electro-transport study of Fe-doped sample
                      shows vanishing AHE below 207 K. Therefore, we conclude that
                      Fe doping significantly influences the magnetic structure in
                      the commensurate region and that AHE completely vanishes in
                      the incommensurate region.},
