Abstract: We study the dynamics of a magnetic domain wall, inserted in, or juxtaposed to, a conventional superconductor, via the passage of a spin polarized current through a ferromagnet-superconductor-ferromagnet junction. Solving the Landau-Lifshitz-Gilbert equation of motion for the magnetic moments, we calculate the velocity of the domain wall and compare it with the case of a ferromagnet-normal-ferromagnet junction. We find that in several regimes the domain wall velocity is higher when it is driven by a supercurrent.
