A ferromagnetic model of kekulene-like nanostructure is established, in which the Ising ring (S = 1) decorated by the edge-spin (S = 3/2) through antiferromagnetic Heisenberg exchange interaction. The thermodynamic properties and magnetization behavior of the system were investigated by use of the exact diagonalization and transfer matrix method. It was found that there are six different phases with different values of magnetic susceptibility multiplied by temperature at low temperature in the parameter space of single-ion anisotropy, but it gets only one value taken in the high-temperature limit. The multi-peak phenomena of the specific heat curve at ultra-low temperature are corresponding to the entropy of the system, which the abundant and dense excited states are near the ground state. It shows many different magnetization plateaus in the magnetization process of the system, but no spontaneous magnetization appears. The number and width of magnetization plateaus and the saturation of the magnetization are affected by the single-ion anisotropy.

建立了类kekulene纳米结构的铁磁模型，其中伊辛环（S = 1）通过反铁磁海森堡交换相互作用被边缘自旋（S = 3/2）修饰。采用精确对角化和传递矩阵法研究了系统的热力学性质和磁化行为。发现有六个不同的阶段具有不同的值在单离子各向异性的参数空间中，磁化率乘以低温时的温度，但在高温极限内只取一个值。超低温比热曲线的多峰现象对应于系统的熵，其丰富而密集的激发态接近基态。它在系统的磁化过程中表现出许多不同的磁化平台，但没有出现自发磁化。磁化平台的数量和宽度以及磁化的饱和度受单离子各向异性的影响。
