  Recently it has been recognized that the electromotive force (emf) can be
induced just by the spin precession where the generation of the electromotive
force has been considered as a real-space topological pumping effect. It has
been shown that the amount of the electromotive force is independent of the
functionality of the localized moments. It was also demonstrated that the rigid
domain wall (DW) motion cannot generate electromotive force in the system.
Based on real-space topological pumping approach in the current study we show
that the electromotive force can be induced by rigid motion of a deformed DW.
We also demonstrate that the generated electromotive force strongly depends on
the DW bulging. Meanwhile results show that the DW bulging leads to generation
of the electromotive force both along the axis of the DW motion and normal to
the direction of motion.
