Abstract
Abstract The induction of electric current between atoms arranged in concentric circles by an external magnetic field is studied using a tight-binding model. In particular, the dependence of electric current on the strength of the magnetic field, number of atoms, and temperature is examined. Substantial changes are observed in the electric current distribution when the difference in the transfer integral along the circumference and between circles is increased. Additionally, the difference in the electric current flow compared with that through a graphene ring is analyzed.
