英文摘要	Exploiting two-dimensional van der Waals (2D vdW) room temperature ferromagnetic materials is always significant and valuable work. However, the actual number of satisfactory materials with intrinsic ferromagnetism is very limited. Here, the 2D layered Cr4Te5 epitaxial films prepared by a pulsed laser deposition technique were confirmed to hold a ferromagnetic ordering state up to 300 K. We find that the Cr4Te5 films can easily achieve epitaxial growth along a single orientation of the hexagonal Al2O3(0001) substrate. However, as for the cubic SrTiO3(001) and multiphase structure mica substrates, the Cr4Te5 films only show uniaxial growth instead of epitaxial growth. Based on the investigation of electronic transport in the metallic regime, it is revealed that the interaction of electron-magnon scattering only exists in the lower temperature region. Our work renders 2D vdW Cr4Te5 crystals a very promising material for developing practical spintronic nanodevices.
