Can vortices in Type II move?

  1. I'm used to astrophysics, where flux tubes in highly conductive materials are said to be "frozen" to such materials because such movement would create a very large amount of eddy currents. So you would think flux tubes in a solid superconductor could not move at all. But it seems that the vortices in Type II superconductors tend move and that some effort is made to pin them.

    What am I missing?

  3. They do indeed move as is seen in this video.
