Nanowire detects Abrikosov vortices

Researchers from the Moscow Institute of Physics and Technology, Lomonosov Moscow State University, and the Institute of Solid State Physics of the Russian Academy of Sciences have demonstrated the possibility of detecting Abrikosov vortices penetrating through a superconductor-ferromagnet interface. The device considered in their study is a ferromagnetic nanowire with superconductive electrodes connected to it.
