我们展示了一种基于以受控方式位移的畴壁尖端的单个磁性微粒的操纵方法。通过施加外部磁场，尖端可以拖动或推动磁性粒子。这种镊子在探测和操纵胶体体系方面具有潜在的应用价值。
We demonstrate a method for manipulation of single magnetic microparticles based on a domain wall tip displaced in a controlled manner. By applying an external magnetic field, the tip can either drag or push magnetic particles. This kind of tweezers has potential applications in probing and manipulating colloidal systems.
