摘　　要：Landau-Lifshitz方程是描述磁性物质动态磁化现象的方程,而研究磁性物质是非常有意义的。目前学者们构造了部分精确解,本文利用Fourier展开研究无外加磁场且耗散项为零时的Landau-Lifshitz方程,给出方程有限项的迭代关系。Landau-Lifshitz equations describes magnetic phenomena of magnetization dynamics equation;studying the material is very meaningful. Scholars have constructed some explicit solutions. In this paper, we study the Landau-Lifshitz equations, which have no external magnetic field and the dissipation term is zero, by Fourier expansion. And we also give the iterative relations of finite terms of the equation.
