Observation of critical magnetic behavior in 2D carbon based composites.

Two dimensional (2D) carbonaceous materials such as graphene and its derivatives, , graphdiyne, have enormous potential possibilities in major fields of scientific research. Theoretically, it has been proposed that the perfect atomic lattice arrangement of these materials is responsible for their outstanding physical and chemical properties, and also for their poor magnetic properties. Experimentally, it is difficult to obtain a perfect atomic lattice of carbon atoms due to the appearance of structural disorder.
