  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.
