标题： Topological magnetism in diluted artificial adatom lattices

摘要： 控制原子尺度物质的能力彻底改变了我们对物理世界的理解，为前所未有的技术进步打开了大门。 量子技术利用量子力学的独特原理，使我们能够以非凡的精度构建和操控原子结构。 在此，我们提出一种自下而上的方法，在Nb(110)表面的稀释吸附原子晶格中创建拓扑磁纹理。 通过精确调节吸附原子间距，可以出现以前无法访问的磁相。 我们的研究结果表明，由Nb基底介导的磁性吸附原子之间的相互作用促进了独特拓扑自旋纹理的形成，例如斯格明子和反斯格明子，包括铁磁和反铁磁的。 由于Nb可以超导，我们的研究结果提供了一个新的平台，为拓扑磁性和超导性的相互作用提供了有价值的见解，为结合自旋电子学应用更广泛地探索拓扑超导性铺平了道路。 显示英文摘要

摘要： The ability to control matter at the atomic scale has revolutionized our understanding of the physical world, opening doors to unprecedented technological advancements. Quantum technology, which harnesses the unique principles of quantum mechanics, enables us to construct and manipulate atomic structures with extraordinary precision. Here, we propose a bottom-up approach to create topological magnetic textures in diluted adatom lattices on the Nb(110) surface. By fine-tuning adatom spacing, previously inaccessible magnetic phases can emerge. Our findings reveal that interactions between magnetic adatoms, mediated by the Nb substrate, foster the formation of unique topological spin textures, such as skyrmions and anti-skyrmions, both ferromagnetic and antiferromagnetic. Since Nb can be superconducting, our findings present a novel platform with valuable insights into the interplay between topological magnetism and superconductivity, paving the way for broader exploration of topological superconductivity in conjunction with spintronics applications.
