abstract = {We carry out density functional theory calculations which
demonstrate that the electron dynamics in the Skyrmion phase
of Fe-rich Mn1−xFexGe alloys is governed by Berry phase
physics. We observe that the magnitude of the
Dzyaloshinskii-Moriya interaction directly related to the
mixed space-momentum Berry phases, changes sign and
magnitude with concentration x in direct correlation with
the data of Shibata et al. [Nat. Nanotechnol. 8, 723
(2013)]. The computed anomalous and topological Hall effects
in FeGe are also in good agreement with available
experiments. We further develop a simple tight-binding model
able to explain these findings. Finally, we show that the
adiabatic Berry phase picture is violated in the Mn-rich
limit of the alloys.},
