Abstract: A system and method for a logic device is disclosed. A first substrate, and a second substrate is provided, which are spaced apart from each other and manifests Spin orbit torque effect. A nanomagnet is disposed over the first substrate and the second substrate. A first charge current is passed through the first substrate and a second charge current is passed through the second substrate. A direction of flow of the first charge current and the second charge current defines an input value of either a first value or a second value. A spin in the nanomagnet is selectively oriented based on the direction of flow of the first charge current and the second charge current. The spin in the nanomagnet is selectively read to determine an output value as the first value or the second value. The logic device is configured as a XOR logic.

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.

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.

Abstract: A system and method for a logic device is disclosed. A substrate is provided. Three nanotracks are disposed over the substrate and intersect in a central portion. Two nanotracks are disposed about a first axis and one nanotrack is disposed about a second axis perpendicular to the first axis. A ground pad is disposed in the central portion. Nanotrack along the second axis extend beyond the central portion to define an output portion. An input value is set by nucleating a skyrmion about a first end of the nanotracks. Presence of the skyrmion indicates a first value and absence indicates a second value. A charge current is passed in the substrate, along the first axis and the second axis to move the nucleated skyrmions towards the central portion. Presence of the skyrmion is sensed in the output portion and indicates a first value when skyrmion is present.

Abstract: A system and method for a memory device is disclosed. A substrate is provided. A nucleation pad is disposed over the substrate. A nanowire is disposed substantially perpendicular, about a center of the nucleation pad. A charge current is selectively passed through the substrate to nucleate a magnetic vortex in the nucleation pad, the magnetic vortex indicative of a magnetic domain and a direction of the magnetic vortex indicative of a polarity of the magnetic domain. A shift current is applied through the nanowire to shift the magnetic domain into the nanowire.
