| Abstract: | We have combined magneto-optical imaging with an ultra-fast heating/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, the dominant force is the magnetic repulsion between vortices. The extent of the motion of individual vortices is consistent with a vortex mass of few electronic masses per lattice constant at 0.97Tc. |
