Abstract
A skyrmion logic gate is provided. The logic gate comprises a first track configured for propagation of magnetic skyrmions and a second track configured for propagation of magnetic skyrmions. A junction links the first and second tracks. A continuous current flows through the logic gate, wherein skyrmions propagate due to the current.
Claims24
A logic gate, comprising:
- a first track configured for propagation of magnetic skyrmions;
- a second track configured for propagation of magnetic skyrmions;
- a junction linking the first and second tracks;
- a continuous current flowing through the logic gate, wherein skyrmions propagate due to the current;
- and
- additional tracks configured for propagation of magnetic skyrmions, wherein one or more additional junctions link together multiple tracks in the logic gate.
3 more elements
A logic circuit, comprising:
- a number of skyrmion logic gates, wherein each skyrmion logic gate comprises:
- three or more tracks configured for propagation of magnetic skyrmions;
- at least two junctions linking multiple tracks together;
- and
- a continuous current flowing through the logic gates, wherein skyrmions propagate due to the current, and wherein output skyrmions from logic gates in the circuit act as input skyrmions for other logic gates in the circuit.
2 more elements
A method of performing logical computations with magnetic skyrmions, the method comprising:
