Vortices Penetrating into a Superconducting Lead Film (image) The Hebrew University of Jerusalem Share Print E-Mail Caption This photo shows four different images of vortices penetrating into a superconducting lead film at rates of tens of GHz, and traveling at velocities up to about 20 km/s. The vortex trajectories, appearing as smeared lines, show a tree-like structure with a single stem that undergoes a series of bifurcations into branches. Each image is done at a different magnetic field and each image is 12 x 12 μm2.
