Abstract
This study used Monte Carlo simulations to delve into the magnetic features of fullerene C60 and graphene nanostructures. Fullerene exhibits a higher blocking temperature (TB) under an external magnetic field (H), indicating increased sensitivity to magnetic ordering at higher temperatures. In contrast, graphene demonstrates a distinct behavioral reversal when H was absent. Both nanostructures exhibit progressive transitions from ferromagnetic to superparamagnetic behavior, with delayed shifts influenced by linear (J) and biquadratic (K) coupling. Fullerene’s flexibility suggests applications in adjustable magnetic systems, while graphene’s stability makes it suitable for high-frequency uses and stable electronics.
本研究利用蒙特卡罗模拟深入研究了富勒烯 C60 和石墨烯纳米结构的磁性特征。富勒烯在外部磁场（H）作用下表现出较高的阻滞温度（TB），表明在较高温度下对磁有序的敏感性增加。相比之下，石墨烯在没有 H 的情况下表现出明显的行为逆转。这两种纳米结构都表现出从铁磁性到超顺磁性的渐进转变，延迟转变受到线性（J）和双四边形（K）耦合的影响。富勒烯的灵活性使其适用于可调磁性系统，而石墨烯的稳定性使其适用于高频应用和稳定的电子器件。
期刊介绍：
The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public.
Main Categories:
Full-length articles:
Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged.
In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications.
The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications.
The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism.
Review articles:
Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
