Abstract
We have combined high-resolution magneto-optical imaging with an ultrafast heating and cooling technique to measure the movement of individual vortices in a superconducting film. The motion took place while the film was heated close to Tc, where pinning and viscous forces are relatively small. Under these conditions, vortices move due to the magnetic repulsion between them. We found that a finite vortex mass has to be included in the analysis in order to account for the experimental results. The extent of the motion is consistent with a vortex mass being three orders of magnitude smaller than the mass of all the electrons in the core.
