Many researchers consider vortices\u2014which can form even in the absence of an external magnetic field\u2014to be the source of this so-called current-induced quenching. But determining how vortices cause quenching requires better knowledge of vortices and thus better measurements of their motion.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new technique reveals high-speed trajectories of oscillating vortices and shows that they are 10,000 times lighter than expected.
