Two-dimensional (2D) ferromagnets exhibit long-range ferromagnetic order which can be manipulated by layer thickness， doping， and strain， and they are potentially useful for developing next-generation spintronic devices. Recently， Cr-based 2D ferromagnets have attracted particular attention， because of their high Curie temperatures (TC). In this talk， I will talk about the fabrication of ferromagnetic thin films by molecular beam epitaxy method and characterized its crystal structure by reflection high energy electron diffraction and low-energy electron diffraction. The temperature dependent electronic structure and band structure evolution of ferromagnetic thin films across TC were carried out by various spectroscopies.
