To reduce the problem that whilst the field necessary to propagate magnetic solitons in a straight line is relatively small, changes in direction, junctions and logic gates will result in poorer coupling between adjacent solitons, the resulting energy discontinuity necessitates higher propagation fields, the gap between propagation and nucleation fields is reduced and a new soliton is erroneously nucleated.
The magnetic logic element for a logic device is described which is formed by at least one conduit capable of sustaining and propagating a magnetic soliton, the conduit being adapted by the provision of nodes and/or directional changes giving rise to discontinuities in soliton propagation energy as a result of which logical functions may be processed. Magnetic logic devices such as interconnects and gates, and magnetic logic circuits incorporating such devices and suitable operational fields, are also described.
