A Berry curvature investigation has been made on the magnetic modulated structures such as
domain walls (DWs) and helimagnetic spin configurations. Results of the present study show that the
geometry of the spin configuration and the direction of the magnetic field creating the spin precession are of crucial importance in the magnitude of obtained electromotive force. It has recently been recognized that
the Rashba coupling increases significantly the electromotive force when this coupling is high enough to give
predominant contribution in the magnetization dynamics. However, in the opposite case when the Rashba
interaction has negligible contribution in the magnetization dynamics it was shown that the magnitude of
the electromotive force decreases slightly by increasing the Rashba coupling strength. Therefore the effect
of the Rashba interaction in the electromotive force of the moving DWs rests largely on the strength and
also effectiveness of this interaction in the magnetization dynamics.
