We applied Monte Carlo simulation to investigate the thermodynamic properties and hysteresis loops of the hexagonal core-shell nanoparticle described by a ferrimagnetic mixed-spin (3/2, 5/2) Ising model. The results revealed the significance of the single-ion anisotropy, exchange coupling, external magnetic field in dominating various thermodynamic quantities and hysteresis loops. We obtained the variation of the critical temperature with various parameters. Under certain parameter conditions, the system may exhibit rich multiple-loop hysteresis behaviors, depending on the competition among the physical parameters.

六边形核壳纳米粒子的热力学性质和滞后回线

我们应用蒙特卡罗模拟来研究由亚铁磁混合自旋 (3/2, 5/2) Ising 模型描述的六边形核壳纳米粒子的热力学性质和磁滞回线。结果揭示了单离子各向异性、交换耦合、外部磁场在支配各种热力学量和磁滞回线中的重要性。我们获得了临界温度随各种参数的变化。在一定的参数条件下，系统可能会表现出丰富的多回路滞后行为，这取决于物理参数之间的竞争。
