摘要：

We study the phenomenon of magnetization reversal in the form of a soliton flip in a biquadratic ferromagnetic spin chain induced by varying bilinear and biquadratic exchange interactions. This is carried out by analyzing the evolution of the velocity and amplitude of the soliton using a perturbation analysis.
