Abstract
A system and method for a logic device is disclosed. Three synthetic antiferromagnet (SAF) nanotracks are disposed over a substrate along a first axis. A connector nanotrack connects the three input nanotrack about a second end of the nanotracks. An output nanotrack is disposed about a central portion of the connector nanotrack. An input value is defined at a first end of the input nanotracks by selectively nucleating a SAF 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. A charge current is passed along the first axis to selectively move nucleated skyrmion to the output nanotrack, with presence of Skyrmion indicating an output value of the first value.
