| Abstract: | 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. |
