Abstract
A system and method for a logic device is disclosed. A first nanotrack along a first axis and a second nanotrack along a second axis perpendicular to the first axis are disposed over a substrate. The second nanotrack is disposed over the first nanotrack in a overlap portion. An input value is defined about a first end of the first nanotrack and the second nanotrack by nucleating a skyrmion, wherein a presence of the skyrmion defines a first value and absence of the skyrmion defines a second value. The nucleated skyrmion moves towards the second end of the nanotracks when a charge current is passed through the first nanotrack and the second nanotrack along the second axis. The presence of the skyrmion sensed at the second end of the nanotrack indicates an output value of the first value.
