结果表明，可以计算的惯性振荡的铁磁畴壁，而不作任何假设的阻尼机制。除了阻尼之外的物理考虑被用来制定适当的近似。讨论了振荡壁面中自旋取向的特殊分布，指出了畴转动与壁面位移之间存在动力学相互作用的可能性。壁在周期运动的惯性被发现同意Döring获得的特殊情况下的匀速运动。它的结论是，惯性只取决于在休息时的墙壁的特性，提供的移动壁的变形是足够小的，以确保运动方程的线性。
It is shown that the inertia of an oscillating ferromagnetic domain wall can be calculated without making any assumptions with regard to the damping mechanism. Physical considerations other than damping are used to formulate appropriate approximations. The particular distribution of spin orientations in an oscillating wall is discussed, and the possibility of dynamic interactions between domain rotations and the wall displacement is pointed out. The inertia of a wall in periodic motion is found to agree with that obtained by Döring for the special case of uniform motion. It is concluded that the inertia depends solely on characteristics of the wall at rest, provided the distortion of the moving wall is sufficiently small to insure the linearity of the equation of motion.
