In past decades, ultra-thin bismuth film has attracted much attention due to its competing 2D structural phases and strong spin orbit coupling (SOC). Remarkably, despite of introducing the topological electronic properties, the strong SOC of Bi may also make the interface of ferromagnetic material (FM) and 2D Bi to be a suitable platform hosting strong Dzyaloshinskii-Moriya interactions (DMI), which is essential for the generation of the magnetic skyrmions. However, due to the severe growth conditions of 2D Bi, it is hard to realize the interface or the superlattice of 2D Bi with the other materials. In this thesis, the intriguing synthesis methods via molecular beam epitaxy (MBE) and the formation mechanism of two different 2D Bi intercalated ferromagnetic systems, including Bi(111) bilayer intercalated Cr2Te3/Bi2Te3 heterostructure and black-phosphorus-like Bi (BP-Bi) intercalated Cr2Te3 thin film, are addressed.
