Multifunctional Spin Logic Operations in Graphene Spin Circuits
Journal article, 2022
Spin-based computing, combining logic and nonvolatile magnetic memory, is promising for emerg-ing information technologies. However, the realization of a universal spin logic operation, representing a reconfigurable building block with all-electrical spin-current communication, has so far remained chal-lenging. Here, we experimentally demonstrate reprogrammable all-electrical multifunctional spin logic operations in a nanoelectronic device architecture, utilizing graphene buses for spin communication and mixing and nanomagnets for writing and reading information at room temperature. This device realizes a multistate spin-majority logic operation, which is reconfigured to achieve (N)AND, (N)OR, and XNOR Boolean operations, depending on the magnetization of inputs. The results are in good agreement with the predictions from a spin-circuit model, providing an experimental demonstration of a spin-based logic unit that takes advantage of the vector nature of spin, as opposed to conventional scalar charge-based devices. These spin logic operations in large-area graphene are fully compatible with industrial fabrication pro-cesses and represent a promising platform for scalable all-electric spin-based logic-in-memory computing architecture.
