Abstract
A method of manufacturing a magnetic wire example includes depositing a magnetic film, which has a composition that enables measuring motion of a magnetic domain wall in the magnetic film, on/above a silicon substrate, forming the magnetic film on the silicon substrate on which the magnetic film is deposited using a wire pattern and an electrode pattern of a certain specification, shielding a central part of the magnetic wire in a photolithography method by an edge milling pattern which corresponds to a predetermined specification, and ablating an edge portion of the magnetic wire which is not shielded by an ion milling.

A method of manufacturing a magnetic wire, the method comprising:
- depositing a magnetic film, which has a composition that enables measuring movement of a magnetic domain wall in the magnetic film, above a silicon substrate;
- forming a magnetic wire on the silicon substrate, above which the magnetic film is deposited, using a wire pattern and an electrode pattern of a predetermined specification;
- shielding a central part of the magnetic wire in a photolithography method by an edge milling pattern corresponding to the predetermined specification;
- and
- ablating an edge portion of the unshielded magnetic wire by ion-milling.
A magnetic wire comprising:
- opposing edge portions, wherein each edge portion is cut in a predetermined width ratio relative to a total width of the magnetic wire so that a magnetic domain wall of the magnetic wire does not tilt due to an Oersted field which occurs due to a current applied to the magnetic wire.
A magnetic wire comprising:
- a magnetic layer of soft magnetic material, wherein the magnetic wire does not require power to persistently store bits in the magnetic layer, and wherein the magnetic wire is configured to allow the bits to move within the magnetic wire when current is applied to the magnetic wire;
- and
- a paramagnetic conductive layer, layered with the magnetic layer, and configured to receive the current, wherein a width of the magnetic layer is less than a width of the paramagnetic conductive layer.
