N2 - Magnetic domain wall motion induced by magnetic fields and spin-polarized electrical currents is experimentally well established. A full understanding of the underlying mechanisms, however, remains elusive. We reported a detail comparison of such motions in the thermally activated subthreshold, or "creep," regime, where the wall velocity obeys an Arrhenius law. Experiment shows the velocity scales in an evidently different way with a driving current and field, proving the nonequivalence of two drives. Scaling theory explains the important features of experiment.
