论文摘要
纳米级磁体组件中的相互作用的能力对于人工旋转系统和自旋技术技术的发展至关重要。在薄膜磁性中的Dzyaloshinskii-Moriya相互作用（DMI）出现之后，已经开了新的途径，通过强手性相互作用将纳米磁体搭配起来，这是与已建立的偶极和交换偶联机制互补的。从这个角度来看，我们回顾了由中间层和内层DMI结合的合成磁体工程的最新进展。我们展示了多层手性磁性结构和二维合成反铁磁铁，天际和人造自旋系统如何通过同时控制DMI和磁各向异性来实现。此外，我们表明，通过DMI和电流诱导的自旋轨道扭矩的组合，可以获得合成磁元素的无场切换以及全电网域壁逻辑电路。
The ability to engineer the interactions in assemblies of nanoscale magnets is central to the development of artificial spin systems and spintronic technologies. Following the emergence of the Dzyaloshinskii-Moriya interaction (DMI) in thin film magnetism, new routes have been opened to couple the nanomagnets via strong chiral interactions, which is complementary to the established dipolar and exchange coupling mechanisms. In this Perspective, we review recent progress in the engineering of synthetic magnets coupled by the interlayer and intralayer DMI. We show how multilayer chiral magnetic structures and two-dimensional synthetic antiferromagnets, skyrmions, and artificial spin systems can be realized by simultaneous control of the DMI and magnetic anisotropy. In addition, we show that, with the combination of DMI and current-induced spin-orbit torques, field-free switching of synthetic magnetic elements is obtained as well as all-electric domain wall logic circuits.
