  We propose a method to all-electrically control a domain-wall position in a
ferromagnetic nanowire with Dzyaloshinskii-Moriya interaction. The strength of
this interaction can be controlled by an external electric field, which in turn
allows a fine tuning of the pinning potential of a spin-spiral domain wall. It
allows to create more mobile pinning sites and can also be advantageous for
ultra-low power electronics.
