In this study, the ground-state phase diagrams and magnetic properties of mixed spin ($S$-1, $\sigma$-7/2) of the monolayer coronene-like nanostructure have been investigated using Monte Carlo simulations (MCS) in the frame of the Blume Capel model. In the first part, ground-state phase diagrams have been analyzed in order to show the more stable configurations of spins corresponding to various planes. In addition, MCS is applied to study the behavior of the compensation and blocking temperatures by varying the exchange coupling interaction values. Finally, the hysteresis cycle behaviors have been investigated for selected values of exchange coupling parameters, temperature and crystal field. The theoretical results obtained in this study can enrich the magnetic properties of nanosystems and pave the way for researchers to experimentally study monolayer coronene-like nanostructure for future applications in nanotechnology.

在这项研究中，混合自旋的基态相图和磁性（$\mathrm{小号}$-1,$\sigma$-7/2) 的单层类晕苯纳米结构已经在 Blume Capel 模型的框架中使用蒙特卡罗模拟 (MCS) 进行了研究。在第一部分中，分析了基态相图，以显示对应于各种平面的自旋的更稳定配置。此外，通过改变交换耦合相互作用值，应用 MCS 来研究补偿和阻塞温度的行为。最后，研究了交换耦合参数、温度和晶体场的选定值的磁滞循环行为。本研究获得的理论结果可以丰富纳米系统的磁性，并为研究人员通过实验研究单层类冕烯纳米结构为未来在纳米技术中的应用铺平道路。
