### Abstract

C_{60} polymerized carbon nanotori and haeckelites nanostructures are investigated when they are exposed to an external magnetic field (B). A π-electron tight binding model in conjunction with the London approximation has been implemented in order to calculate the ring currents produced by the magnetic field B and thus, we determined the diamagnetic or paramagnetic response as a function of the carbon atomic arrangement. We have found that magnetic response depends strongly of the morphology of the carbon nanostructures. The results obtained for corrugated rings formed by C _{60} joined by 2-fold, 3-fold, and 5-fold symmetry axis. In this case, we found that when C_{60} is joined, by the 5-fold axis (by means of pentagonal rings), nanotori structures exhibit strong current fluxes that favor the generation of large magnetic moments perpendicular to the ring plane. When the C_{60} is joined trough the 2-fold or 3-fold axis of symmetry, the corrugated rings exhibit interesting ring patterns which depend of the number of C_{60} molecules. In addition, electronic and magnetic properties of haeckelite type tori are discussed.
