Using Monte Carlo simulation, we investigated magnetic and thermodynamic characteristics of the rectangle core–shell ferrimagnetic mixed-spin (3/2, 2) Ising nanoribbon under the effects of sublattice crystal field, exchange coupling and temperature. Typical temperature dependence of the total magnetization, the core and shell magnetization, the susceptibility and the internal energy for several fixed values of Hamiltonian parameters were discussed in detail. The phase diagrams of the critical and compensation temperatures were presented in various Hamiltonian parameter planes. In addition, particular emphasis was given to the interesting multi-cycle hysteresis behaviors of the total system and sublattices. Our results show reasonable consistency compared with many previous theoretical and experimental studies.

使用蒙特卡洛模拟，我们研究了亚晶格晶体场，交换耦合和温度影响下矩形核-壳亚铁磁性混合自旋（3/2，2）Ising纳米带的磁和热力学特性。详细讨论了总的磁化强度，核和壳的磁化强度，磁化率和内能对典型汉密尔顿参数的几个固定值的典型温度依赖性。临界温度和补偿温度的相图在各种哈密顿量参数平面中给出。此外，还特别强调了整个系统和子格的有趣的多周期磁滞行为。与许多先前的理论和实验研究相比，我们的结果显示出合理的一致性。
