We have investigated the velocity of magnetic domain wall (DW) motion induced by electric currents in a Co/Ni nanowire with a perpendicular magnetic anisotropy. The DW velocity increased as current density increased and the maximum velocity of 60 m/s was observed. Furthermore, the DW velocity was found to be almost independent of external perpendicular magnetic fields in the range of -50 to +50 Oe. The mechanism of the observed field insensitivity of the current induced DW motion is also discussed. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3590713]
