Abstract
The present invention is directed towards a tubular nanosized magnetic wire, wherein the nanosized magnetic wire comprises: a tubular magnetic shell surrounding a longitudinal axis of the wire, at least one region of the tubular magnetic shell is capable of providing a 360° magnetic domain wall, wherein the 360° magnetic domain wall is self-stabilizing and has a magnetization going from a parallel alignment to a perpendicular alignment and to a parallel alignment with regards to the wire axis. The present invention also provides a practical method capable of making a tubular nanosized magnetic wire with a self-stabilizing, 360° magnetic domain wall. The present invention also relates to the use of the tubular nanosized magnetic wire in a racetrack memory device.
