近邻相互作用对混合自旋Blume-Capel模型磁化强度的影响

利用有效场论研究了最近邻原子间的相互作用对纳米管晶格点磁化强度的影响。结果表明，最近邻交换相互作用和晶体场强度相互竞争，使系统表现出丰富的磁化特性。当负晶体场作用于系统时，系统发生一阶相变。当晶体场的参数和交换相互作用不同时，系统的磁化强度有显著差异。

Effect of near-neighbor interaction on magnetization of hybrid spin Blume-Capel model

The effect of the exchange interaction between the nearest neighbor atoms on the nanotubes on the magnetization of lattice points in the Blume-Capel model was studied by using the effective field theory. The results show that the nearest neighbor exchange interaction and the strength of crystal field compete with each other, which makes the system show rich magnetic characteristics. When the negative crystal field acts on the system, the first order phase transition occurs. The magnetization of the system is remarkably different when the parameters of the crystal field and the exchange interaction are different.
