| 摘 要： | 利用有效场理论研究了纳米管上最近邻原子间弱交换相互作用对Blume-Capel模型磁化强度的影响，得到了系统格点的磁化强度与最近邻弱交换相互作用和晶场强度的关系。结果表明：最近邻弱交换相互作用和晶场强度等诸多因素相互竞争，使系统表现出丰富的磁学特性。正晶场促进系统的磁化强度，而负晶场对其有抑制作用；负晶场作用下，磁化强度基态饱和值小于1，且系统发生一级相变；不同位置的弱交换相互作用对系统的磁化强度影响程度不同。

| Abstract: | The effect of weak exchange between nearest-neighbor atoms on magnetization of Blume-Capel model was studied by using effective field theory. The results show that many factors such as weak exchange interaction and crystal field intensity compete with each other, which makes the system exhibit abundant magnetic characteristics. The positive crystal field promotes the magnetization of the system, while the negative crystal field inhibits it. Under the action of negative crystal field, the ground state saturation value of magnetization intensity is less than 1, and the system has a first-order phase transition. The influence of the weak exchange interaction on the magnetization of the system is different. |
