In a study published in Advanced Materials, a research team led by Prof. Luo Xuan from Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences made a breakthrough in tuning electronic properties of Weyl semimetal Td-MoTe2 by intercalating 3d-element Fe atoms into the van der Waals (vdW) gap, which brought about exotic electronic behaviors as well as the first-time observed magnetic states in the topologically nontrivial Td phase.
