摘要

This paper presents a Monte Carlo simulation study of the hysteresis properties of graphene nanostructures, specifically zigzag, armchair, and reczag configurations. The study investigates the effects of key parameters, considering the role of magnetic exchange interactions (J, K), temperature (T), and the crystal field (D) in modulating the coercivity and saturation field characteristics of the nanostructures. The Blume-Emery-Griffiths model is employed to simulate the magnetic behavior of the systems, which are modeled as spin-1 analogs. The findings aim to provide insights into the magnetic stability and control of graphene-based nanostructures for potential applications in spintronic devices, magnetic storage, and sensor technologies.
