英文摘要	The 2D graphdiyne has attracted much attention in spin-dependent physical properties recently due to its superior intrinsic semiconductor properties and greater paramagnetic moment compared with graphene. However, to date, no ferromagnetic ordering has been successfully induced into graphdiyne (GDY), which restricts its further application in electronics involving spin. Herein, we for the first time obtain the ferromagnetic graphdiyne based on transition metal ferrum (Fe) doping through a simple and affordable synthetic route. In particular, by means of chemical reduction with heat-treatment in the special carbon matrix of graphdiyne, a typical ferromagnetic curve with T-c above room temperature is observed in Fe/GDY hybrid, which can be attributed to the presence of low valence Fe ions. After annealing, the remanent magnetization of Fe/GDY increases and the coercive field reduces by an order of magnitude compared with the raw Fe/GDY hybrid even at 300 K, establishing the robust room temperature ferromagnetic characteristics. Subsequent spin-polarized DFT calculation further supports our conclusion that the observed ferromagnetism originates from the remarkable local magnetic moment as well as the electron transfer between carbon atoms and ferric ions. The coexistence of ferromagnetism and semiconductivity can not only promote exploration of new physical property of GDY but also develop spintronic devices based on carbon materials.
