Abstract
Using density functional theory (DFT) we show that intrinsic ferromagnetism in two-dimensional (2D) carbon semiconducting structures can be achieved by linking triangular graphene nanoflakes (GNFs) with carbon chains containing an odd number of carbon atoms. The observed magnetism can be understood from the singlet-triplet rule of C chain, the anti-pattern rule for a magnetic bipartite C structure, and the Lieb-Mattis criterion. Monte Carlo (MC) simulations indicate that the 2D frameworks can display transitions from a high-spin state to a low-spin state and to a paramagnetic state as temperature increases.
