Intercalation has become a powerful approach to tune the intrinsic properties and introduce novel phenomena in layered materials. Intercalating van der Waals (vdW) magnetic materials is a promising route to engineer the low-dimensional magnetism. Recently, metal thiophosphates,P, has been widely studied because their magnetic orders are highly tunable and persist down to the two-dimensional limit. In this work, we used electrochemical technique to intercalate Li into NiPSsingle crystals and found the emergence of ferrimagnetism at low temperature in Li-intercalated NiPS. Such tuning of magnetic properties highlights the effectiveness of intercalation, providing a novel strategy to manipulate the magnetism in vdW magnets.
嵌入已成为调节层状材料固有特性并引入新现象的有力方法。嵌入范德华（vdW）磁性材料是设计低维磁性的一条有前途的途径。最近，金属硫代磷酸盐受到了广泛研究，因为它们的磁序具有高度可调性，并且在二维极限下依然存在。在这项工作中，我们使用电化学技术将锂嵌入NiPS单晶中，发现在嵌入锂的NiPS中低温下出现了亚铁磁性。这种磁性能的调节突出了嵌入的有效性，为操纵vdW磁体中的磁性提供了一种新策略。
