摘　　要：采用Holstein Primakoff变换、相干态表示、含时微扰原理和多重标度方法 ,研究了Aharonov Bohm(A B)磁通对一维铁磁链中的磁隙孤子产生的影响 ,得到了在A B磁通影响下的磁隙孤子的峰值、宽度。Employing Holstein-Primakoff transformation, the coherent state ansatz, the time dependent variational principle and the method of multiple-scales, we have studied the effects of the Aharonov-Bohm flux on the soliton in ferromagnetic chain. The results show that the Aharonov-Bohm flux have an effect on the peak,the width, the energy and the spatial configuration of the spin of the soliton.
