Abstract :
The underlying mechanisms for domain wall propagation induced by spin-polarized currents were studied. The critical parameters for current-induced wall motion such as the threshold current density at which the motion sets in, the wall velocity and their temperature dependence, were obtained experimentally. Permalloy rings with nonmagnetic contacts were fabricated for transport measurements.
