  • Publication number: 20240120923
    Abstract: Provided are a spin logic device based on a magnetic tunnel junction and an electronic apparatus comprising the same. According to an embodiment, the spin logic device may comprise: a current wiring; a magnetic tunnel junction, which comprises a free magnetic layer, a fixed magnetic layer, and a potential barrier layer located therebetween, which are stacked on the current wiring; and a current source for providing an input current to the current wiring, wherein the input current comprises a first, a second, and a third in-plane currents, directions of which are different from a direction of a magnetization axis of the free magnetic layer or there is a vertical component in that direction, and the first and the second in-plane currents are logical input currents while the third in-plane current is used to control the implementation mode of the spin logic device.
