Van der Waals materials of the MB2T4 family (M = transition metal or rare-earth metal, B = Bi or Sb, T = Te, Se, or S) have attracted interest for their magnetic and topological properties, but their direct synthesis into 2D form remains challenging. Here the authors report a flux-assisted, phase-controlled growth strategy to directly grow six magnetic 2D MB2T4 crystals.
