最近邻相互作用对混合自旋 Blume-Capel模型磁化强度的影响
Effect of near-neighbor interaction on magnetization of hybrid spin Blume-Capel model
摘要
Abstract
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 re-sults show that the nearest neighbor exchange interaction and the strength of crystal field compete with each oth-er, which makes the system show rich magnetic characteristics. When the negative crystal field acts on the sys-tem , the first order phase transition occurs. The magnetization of the system is remarkably different when the pa-rameters of the crystal field and the exchange interaction are different.关键词
