论文摘要
材料中不同外来特性的组合为出现新潜在应用的出现铺平了道路。一个例子是最近发现的氢化硼型钻石中相互拮抗的铁磁和超导性的共存，该钻石有望成为一种有吸引力的系统，可以探索非常规物理学。在这里，我们通过扫描隧道谱图显示了Yu-Shiba-Rusinov（YSR）带有数十个纳米纳米的空间范围的Yu-Shiba-Rusinov（YSR）带的出现。从理论上讲，我们在三维（3D）超导体表面的二维（2D）自旋晶格如何产生YSR频段，以及它们的密度态谱与自旋晶格结构如何相关。实现铁磁性和超导性共存的新形式的既定策略为设计不寻常的电子状态并设计出更好执行的超导设备的方式开辟了一种方法。
The combination of different exotic properties in materials paves the way for the emergence of their new potential applications. An example is the recently found coexistence of the mutually antagonistic ferromagnetism and superconductivity in hydrogenated boron-doped diamond, which promises to be an attractive system with which to explore unconventional physics. Here, we show the emergence of Yu-Shiba-Rusinov (YSR) bands with a spatial extent of tens of nanometers in ferromagnetic superconducting diamond using scanning tunneling spectroscopy. We demonstrate theoretically how a two-dimensional (2D) spin lattice at the surface of a three-dimensional (3D) superconductor gives rise to the YSR bands, and how their density-of-states profile correlates with the spin lattice structure. The established strategy to realize new forms of the coexistence of ferromagnetism and superconductivity opens a way to engineer the unusual electronic states and also to design better performing superconducting devices.
