Abstract
A system and method for a logic device is disclosed. A plurality of synthetic antoferromagnet (SAF) nanotracks including 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 SAF 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 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 move nucleated skyrmion to the second end of the output nanotrack. Skyrmion at the output indicates an output value of the first value.
