论文摘要
在插入的过渡金属二核苷（I-TMDC）中，过渡金属插入引入了磁相，在某些情况下会诱导拓扑带交叉。但是，在这种材料中，拓扑特性仍然难以捉摸。在这里，我们采用角度分辨的光发射光谱，以揭示外延生长的铁磁CR1/3NBSE2的带结构。 Weyl交叉的实验证据表明，CR1/3NBSE2是拓扑铁磁铁。这项工作强调了I-TMDC作为低维系统中磁性和拓扑物理相互作用的平台。
In intercalated transition metal dichalcogenides (I-TMDC), transition metal intercalation introduces magnetic phases which in some cases induce topological band crossing. However, evidence of the topological properties remains elusive in such materials. Here we employ angle-resolved photoemission spectroscopy to reveal the band structure of epitaxially grown ferromagnetic Cr1/3NbSe2. Experimental evidence of the Weyl crossing shows Cr1/3NbSe2 to be a topological ferromagnet. This work highlights I-TMDC as platform towards the interplay of magnetic and topological physics in low-dimensional systems.
