摘要

本研究利用混合自旋Blume-Capel模型中的蒙特卡罗模拟，探索了二维类三角形纳米结构的磁性。我们系统地分析了晶体场(D)、外磁场(H)和各向异性交换耦合（Jxx和Jxy）对系统磁性行为的影响。基态相图确定了零温度下稳定的自旋构型，而温度相关的研究揭示了磁化、磁化率和磁滞的变化。我们的发现为控制类三角烯纳米结构的磁响应提供了有价值的见解，这在自旋电子学、纳米级磁存储和低维磁性方面有很大的应用前景。

Magnetic behavior in 2D triangulene-like nanostructures: A Monte Carlo simulation approach

This study explores the magnetic properties of a two-dimensional triangulene-like nanostructure using Monte Carlo simulations within a mixed-spin Blume-Capel model. We systematically analyze how the crystal field (D), external magnetic field (H), and anisotropic exchange couplings (J_xx and J_xy) affect the system’s magnetic behavior. Ground-state phase diagrams identify stable spin configurations at zero temperature, while temperature-dependent studies reveal changes in magnetization, susceptibility, and hysteresis. Our findings offer valuable insights into controlling the magnetic response of triangulene-like nanostructures, which are promising for applications in spintronics, nanoscale magnetic storage, and low-dimensional magnetism.
