Possible magnetic states in buckybowl molecules

Possible magnetic properties are studied in the buckybowl molecules: the sumanene and a part of C_60. The Hubbard model is applied to the systems. We find that the molecular structure determines the magnetism in the sumanene. On the other hand, the edge state is found along the zigzag edge of a part of C_60. Therefore, the novel property, transition from molecular magnetism to the magnetism like in nanographene, is found.
