Abstract Submitted to the ; NANOTUBE'05 Conference:

In a 3-D space there are just three geometries possible: Euclidean, spherical and hyperbolic and all the forms we find in nature are realizations of these geometries. At the atomic scale, there are layered materials which can acquire different curvatures contained in the three geometries mentioned above. In this work we study the electromagnetic properties of several curved carbon nanostructures showing that by having control on the curvature, we would be able to generate new materials with new shapes and amazing electronic and magnetic behaviours. In particular, the posibility of having magnetism in curved carbons is analyzed. In this context, a possible explanation of the magnetism found in the rombohedral phase of C60 is given.
