Abstract
A system and method for a logic device is disclosed. A first input nanotrack, a second input nanotrack and an output nanotrack are disposed over a substrate along a first axis. Output nanotrack is disposed between the input nanotracks. Each nanotrack have a first end and a second end. A connector nanotrack connects the first input nanotrack, the second input nanotrack, and the output nanotrack. An input value is defined at a first end of the input nanotracks by selectively nucleating a skyrmion at the first end. Presence of the skyrmion is indicative of a first value and absence of the skyrmion indictive of a second value. Nucleated skyrmion moves to the second end of the output nanotrack when a charge current is passed along the first axis. Presence of the skyrmion at the second end indicates an output value of the first value.
