Current-induced motion and pinning of domain walls in spin-valve nanowires studied by XMCD-PEEM

Original language description

Very large average velocities, up to 600 m/s, have been found for domain-wall motion driven by 3-ns-long pulses of electric current in zero magnetic field in the NiFe layer of 200-nm-wide NiFe/Cu/Co nanowires. For longer pulses, the domain-wall motion isstrongly hindered by pinning potentials. Dipolar interactions between the NiFe and Co layers caused by anisotropy inhomogeneities have been identified as the most important among the different potential sources of DW pinning. The omain-wall velocities increase with current density, but a substantial drop is observed at current densities above 4. 1011 A/m2.
