Abstract

Two-dimensional ferromagnetic metal-free materials possessing only an s/p electronic configuration with weak spin–orbit coupling and a large spin relaxation time play a crucial role in constructing future spintronic devices. Here, we demonstrate a novel two-dimensional material, fluorinated graphitic carbon nitride (g-C3N4) nanosheets, with intrinsic ferromagnetism; its Curie temperature can reach as high as 700 K. More surprising is that such unusual ferromagnetism can be further tuned by changing the concentration of fluorine. The tuneable electronic spin polarization, as well as the ferromagnetism observed in the fluorinated g-C3N4 nanosheets is quite promising for future device applications in spintronics.
