自旋电子学研究的一个最终目标是实现原子尺度的全自旋器件的概念。我们将自下而上的原子制造与自旋分辨扫描隧道显微镜相结合，构建并读出执行逻辑运算的原子级模型系统。我们的概念使用衬底介导的间接交换耦合来实现单个原子自旋之间的逻辑互连。与旋转受挫相结合，这个概念实现了输入之间的各种逻辑运算，例如NOT和OR。
An ultimate goal of spintronic research is the realization of 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 atomic-scale model systems performing logic operations. Our concept uses substrate-mediated indirect exchange coupling to achieve logical interconnection between individual atomic spins. Combined with spin frustration, this concept enables various logical operations between inputs, such as NOT and OR.
