论文摘要
由旋转频率相互作用引起的天空素的惯性质量精确地计算出在铁磁膜中的磁弹性耦合的玩具模型中。质量缩放为磁弹性耦合的强度的平方，作为膜厚度的平方，也是天空横向大小的第一个功率。对于纳米天线，它在几个电子质量的球场中，但在具有较大磁盘的材料中可能会明显更大。这些发现有望代表实际材料中自旋相互作用的任何复杂结构。根据天空处理信息处理速度时，必须考虑它们。
Inertial mass of a skyrmion arising from spin-phonon interaction is computed exactly within a toy model of the magnetoelastic coupling in a ferromagnetic film. The mass scales as the square of the strength of the magnetoelastic coupling, as the square of the film thickness, and as the first power of the lateral size of the skyrmion. For nanometer skyrmions it is in the ballpark of a few electron masses but may be significantly greater in materials with large magnetostriction. These findings are expected to stand for any complex structure of spin-phonon interaction in real materials. They must be taken into account when addressing the speed of information processing based upon skyrmions.
