Theoretical Study of the Magnetic Properties of a Ferrimagnetic Graphene-Like Nanoribbon: Monte Carlo Treatment

Abstract

Monte Carlo simulation was used to study the magnetic properties of the zigzag graphene-like nanoribbon predicated on the ferrimagnetic (5/2,3/2) combined Ising system. The magnetic and thermodynamic properties curves induced by varying exchange coupling interactions and ion anisotropies have all been well studied. For several physical parameters, phase diagrams were provided. Values of exchange couplings and single-ion anisotropy thresholds, indicating whether the system has two compensation temperature points, have been determined. In addition, the impacts of different Hamiltonian parameters on the behavior of multiple-loop hysteresis were explored.
