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. The study reveals that zigzag ribbons exhibit edge states, strongly localized near the zigzag edges, which behave like zero-field edge states with q internal degrees of freedom when a rational fraction of the magnetic flux ($\phi = p/q$) is applied. The orbital diamagnetic susceptibility strongly depends on the edge shape, influenced by the ring currents sensitive to the lattice topology near the edge. The susceptibility is scaled by temperature, Fermi energy, and ribbon width. Zigzag ribbons with edge states show a Curie-like temperature dependence of the Pauli paramagnetic susceptibility, leading to a crossover from high-temperature diamagnetic to low-temperature paramagnetic behavior. The paper also discusses the energy spectrum and dispersion in a magnetic field, the orbital diamagnetic properties, and the Pauli susceptibility, providing insights into the magnetic properties 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.
