摘要: An ultimate goal of spintronic research is the realization concepts for atomic-scale all-spin-based devices. We combined bottom-up atomic fabrication with spin-resolved scanning tunneling microscopy to construct and read out model systems performing logic operations. Our concept uses substrate-mediated indirect exchange coupling achieve logical interconnection between individual spins. Combined spin frustration, this enables various operations inputs, such as NOT OR.
