This animation shows a simple example of how spins could be manipulated with a superconducting layer. It shows just one magnetic flux tube, which moves in a nanoscale channel etched into the surface of the superconductor. When an electric current is sent through the superconductor (moving red arrows) the electromagnetic force moves the flux tube to one side. As it goes, it drags along the patch of spins it has created in the DMS layer underneath. When the current stops, the flux tube stays put. Likewise, a current flowing in the opposite direction moves the flux tube back to the other side.
