In the past few years, there have been a number of proposals for fabricating magnetic memories based on the current-induced motion of magnetic domain walls. A device that uses a novel geometry for injecting electrical currents into the sample is shown to work with current densities that are two orders of magnitude lower than in previous approaches.

We report on a multilevel storage device based on a magnetic tunnel junction (MTJ). Six different resistance states have been observed by controlling domain wall motion in the free layer of a MTJ. It
High domain wall velocities via spin transfer torque using vertical current injection
Using time-resolved magnetotransport measurements, it is shown that vertical injection of spin currents through a magnetic tunnel junction can drive domain walls over hundreds of nanometers at ~500 m/s using current densities on the order of 6 MA/cm2.

Fast Magnetic Domain-Wall Motion in a Ring-Shaped Nanowire Driven by a Voltage.
Using a ring-shaped, rough-edged magnetic nanowire on top of a piezoelectric disk, this work demonstrates a fast voltage-driven magnetic domain-wall motion with average velocity up to 550 m/s, which is comparable to current-driven wall velocity and suggests a new route toward developing high-speed, low-power-dissipation domain- wall spintronics.

Magnetic domain walls in confined geometries have attracted much interest in the last couple of years for a number of reasons. On the one hand, new physical phenomena such as current-induced domain

For racetrack memories based on current-driven propagation of transverse domain walls (TDWs), the central demand is to efficiently reduce current density meanwhile maintaining high enough TDW

Current driven domain wall velocities exceeding the spin angular momentum transfer rate in permalloy nanowires.
High current driven domain wall velocities exceed the estimated rate at which spin angular momentum is transferred to the domain wall from the flow of spin polarized conduction electrons, suggesting that other driving mechanisms, such as linear momentum transfer, need to be taken into account.
