摘要

本文介绍了石墨烯纳米结构的磁滞特性的蒙特卡罗模拟研究，特别是之字形，扶手椅和reczag配置。考虑到磁交换相互作用（J， K）、温度(T)和晶体场(D)对纳米结构矫顽力和饱和场特性的调节作用，研究了关键参数的影响。采用Blume-Emery-Griffiths模型来模拟系统的磁性行为，并将其建模为自旋为1的类似物。这些发现旨在为石墨烯纳米结构在自旋电子器件、磁存储和传感器技术中的潜在应用提供磁稳定性和控制方面的见解。

Monte Carlo Simulations of Hysteresis Properties in Graphene Nanostructures: Comparing Zigzag, Armchair, and Reczag Configurations

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.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
