Abstract
Embodiments are directed to injecting domain walls in a magnetic racetrack memory. In some embodiments, a racetrack comprising a nanowire is coupled with a gate in order to manipulate an anisotropy associated with the nanowire. The racetrack and gate is coupled with a pinning layer configured to establish a magnetization direction in the nanowire.
Claims14
A method for injecting domain walls in a magnetic racetrack memory comprising:
- coupling a racetrack comprising a nanowire with a gate in order to manipulate an anisotropy associated with the nanowire;
- and
- coupling the racetrack and gate with a pinning layer configured to establish a magnetization direction in the nanowire.
-14. (canceled)
A computer program product for injecting domain walls in a magnetic racetrack memory, the computer program product comprising a non-transitory computer readable storage medium having program code embodied therewith, the program code executable by a device to:
- couple a racetrack comprising a nanowire with a gate in order to manipulate an anisotropy associated with the nanowire;
- and
- couple the racetrack and gate with a pinning layer configured to establish a magnetization direction in the nanowire.
