Abstract

A partial differential equation modeling the motion of a domain wall taking into account external magnetic fields and damping is considered. In the case of constant coefficients, this equation has a set of trivial solutions—equilibria. Solutions in the form of simple (traveling) waves that correspond to a dynamic transition from one equilibrium to another are studied. Possible types of waves that are stable in linear approximation are listed. A method for calculating the velocity of such waves is given.

域壁模拟:磁动力学方程中的简单波
摘要 考虑到外部磁场和阻尼,研究了一个模拟域壁运动的偏微分方程。在系数恒定的情况下,该方程有一组微不足道的解--平衡。研究了与从一个平衡到另一个平衡的动态过渡相对应的简单(行进)波形式的解。列出了在线性近似中稳定的波的可能类型。给出了计算这种波的速度的方法。
