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.},
