A method and structure for depinning a domain wall that is in spatial
confinement by a pinning potential to within a local region of a magnetic
device. At least one current pulse applied to the domain has a pulse
length sufficiently close to a precession period of the domain wall
motion and the current pulses are separated by a pulse interval
sufficiently close to the precession period such that: the at least one
current pulse causes a depinning of the domain wall such that the domain
wall escapes the spatial confinement; and each current pulse has an
amplitude less than the minimum amplitude of a direct current that would
cause the depinning if the direct current were applied to the domain wall
instead of the at least one current pulse. The pulse length and pulse
interval may be in a range of 25% to 75% of the precession period.
