In pure carbon materials, such as fullerenes and highly oriented pyrolytic graphite (HOPG), novel magnetic and electrical properties have recently been discovered. In particular, the discovery of weak ferromagnetism in rhombohedral C-60 polymers (Rh-C-60) has attracted the attention of the scientific community and the press. In this paper, the ferromagnetic correlations found in HOPG and Rh-C-60 are commented upon.
