This paper investigates the electronic and magnetic properties of nanographite ribbons with zigzag and armchair edges in a magnetic field using a tight-binding model. One of the key features of these systems is the presence of edge states, which are strongly localized near zigzag edges. These edge states generate a rational fraction of the magnetic flux in each hexagonal plaquette of the graphite plane and behave like zero-field edge states with q internal degrees of freedom. The orbital diamagnetic susceptibility strongly depends on the edge shape and is sensitive to the lattice topology near the edge. The susceptibility is scaled as a function of temperature, Fermi energy, and ribbon width. The edge states lead to a sharp peak in the density of states at the Fermi level, resulting in a Curie-like temperature dependence of the Pauli paramagnetic susceptibility for zigzag ribbons. This indicates a crossover from high-temperature diamagnetic to low-temperature paramagnetic behavior in nanographite ribbons with zigzag edges. The study also shows that the magnetic susceptibility is the sum of orbital diamagnetic and Pauli paramagnetic contributions. The Pauli susceptibility is found to have a Curie-like temperature dependence due to the sharp DOS peak at the Fermi level. The orbital diamagnetic susceptibility is sensitive to the size and edge shape of the ribbons, and the flow of diamagnetic ring currents depends on the lattice topology near the edges. The results suggest that the magnetic properties of nanographite ribbons are significantly influenced by the edge states, and the observed susceptibility is a combination of both orbital and Pauli contributions. The study also highlights the importance of edge states in determining the magnetic behavior of nanographite ribbons.This paper investigates the electronic and magnetic properties of nanographite ribbons with zigzag and armchair edges in a magnetic field using a tight-binding model.
