Can Vortices in Type II Superconductors Move?

[Hornbein]

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?

They do indeed move as is seen in this video.
