Electric current exerts torques-so-called spin transfer torques (STTs)-onmagnetic domain walls (DWs), resulting in DW motion. At low current densities,the STTs should compete against disorders in ferromagnetic nanowires but thenature of the competition remains poorly understood. By achievingtwo-dimensional contour maps of DW speed with respect to current density andmagnetic field, here we visualize unambiguously distinct roles of the twoSTTs-adiabatic and nonadiabatic-in scaling behaviour of DW dynamics arisingfrom the competition. The contour maps are in excellent agreement withpredictions of a generalized scaling theory, and all experimental data collapseonto a single curve. This result indicates that the adiabatic STT becomesdominant for large current densities, whereas the nonadiabatic STT-playing thesame role as a magnetic field-subsists at low current densities required tomake emerging magnetic nanodevices practical.
