Phys. Rev. Lett. 91, 208302 (2003) [4 pages]Domain Wall Tip for Manipulation of Magnetic ParticlesReceived 28 March 2003; published 12 November 2003 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. © 2003 The American Physical Society URL:
