Possible Magnetic States in Buckybowl Molecules

Abstract

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.
