Query: Spin motive force by the momentum-space Berry phase in magnetic Weyl
  semimetals   We show that the magnetic precession of ferromagnetic moments in a
noncentrosymmetric magnetic Weyl semimetal induces an electric current through
a mechanism analogous to the adiabatic charge pumping. The current is a
consequence of a Berry phase in the momentum space resulting from the circular
motion of Weyl nodes induced by the precession. This mechanism resembles the
Faraday effect, namely, induced magnetic field by circular electric current.
The circular motion of Weyl nodes induces magnetic charge current in the
momentum space, which results in a Berry phase that describes the adiabatic
pump. Experimentally, this phenomenon is similar to spin motive force, which is
an electric current induced by magnetic precision in the presence of the
spatial gradient of magnetization. However, unlike the conventional spin motive
force, this current occurs without a magnetization gradient. The result
demonstrates a nontrivial interplay between the topological electronic state
and magnetic dynamics.
