| 摘 要： | 利用MonteCarlo模拟研究了具有4-自旋相互作用Ising模型的磁学性质．模型建立在平面蜂窝状晶格上，除了考虑对相互作用以外，还考虑了四自旋相互作用．给出了不同四自旋相互作用下系统的磁化强度、磁内能、磁比热、磁化率以及转变温度等物理量．结果表明，4-自旋之间的相互作用对Ising模型的性质有很大影响，但基本上是定量的．Monte Carlo模拟的结果对有效场理论（EFfr）的结果给出了很大的修正。

| Abstract: | The magnetic properties of Ising model with four-spin interaction on the honeycomb lattice are studied using the Monte Carlo (MC) method. We consider both pair interaction and four-spin interaction of the system. Magnetic properties of the system with different four-spin interaction such as magnetization,internal energy,specific heat,susceptibility and critical temperature are obtained. The results show that the four-spin interaction influences the magnetic properties of system dramatically, however the influence is basically quantitative. The simulation result by MC method makes a big modification to that of EFT. |
