磁性粒子是未来自旋电子器件中理想的信息载体，近年来引起了人们的广泛关注。由于它们的拓扑保护，磁天幕的产生和湮灭一直是一项具有挑战性的任务。在这里，我们在数值上证明了用静态单轴应变/应力脉冲切断手性条纹域可以产生磁性斯基米子。这一机制不仅为磁性纳米结构提供了一种制造纳米粒子的方法，而且为设计可调谐的纳米粒子机械装置提供了有希望的途径。
Magnetic skyrmions are envisioned as ideal candidates as information carriers for future spintronic devices, which have attracted a great deal of attention in recent years. Due to their topological protection, the creation and annihilation of magnetic skyrmions have been a challenging task. Here, we numerically demonstrate that a magnetic skyrmion can be created by chopping a chiral stripe domain with a static uniaxial strain/stress pulse. This mechanism not only provides a method to create skyrmions in magnetic nanostructures but also offers promising routes for designing tunable skyrmionic-mechanic devices.
