Joined nano-triangles pave the way to magnetic carbon materials

Graphene, a two-dimensional honeycomb structure made of carbon atoms with a thickness of only one atom, has numerous outstanding properties. These include enormous mechanical resistance and extraordinary electronic and optical ...

Unraveling the magnetism of a graphene triangular flake

Graphene is a diamagnetic material, this is, unable of becoming magnetic. However, a triangular piece of graphene is predicted to be magnetic. This apparent contradiction is a consequence of "magic" shapes in the structure ...
