Abstract

This study investigates the magnetic hysteresis properties of the C₆₀ and (C₆₀)₂ fullerene nanostructures according to the Blume–Emery–Griffiths model and Monte Carlo simulations. It seeks to know the influence of parameters such as exchange couplings, crystal field, and temperature on the magnetism of such materials. It was found that C₆₀ exhibited greater coercive and saturation fields than (C₆₀)₂ due to intra-cluster couplings and greater anisotropy. These results provide better understanding of the role of thermal fluctuations and structural stresses in magnetization reversal, which is crucial for magnetic nanomaterials development. These can be employed in spintronic devices, magnetic sensors, memory devices, nanoelectronics, and quantum computing.

C60和二聚（C60）2富勒烯体系磁滞回的比较蒙特卡罗分析

本文采用blme - emery - griffiths模型和Monte Carlo模拟方法研究了C60和（C60）2富勒烯纳米结构的磁滞特性。它试图了解诸如交换耦合、晶体场和温度等参数对此类材料磁性的影响。由于簇内耦合和各向异性，C60比（C60）2具有更大的矫顽力和饱和场。这些结果有助于更好地理解热波动和结构应力在磁化反转中的作用，这对磁性纳米材料的开发至关重要。这些材料可用于自旋电子器件、磁传感器、存储器件、纳米电子学和量子计算。图形抽象
