Superconductivity and Ferromagnetism were long thought to be opposing states of matter, which are mutually incompatible. Latest research suggests, however, that superconductivity and ferromagnetism can coexist under certain conditions. This creates the foundations of fundamentally new classes of superconducting spin-electronic devices, which are based on the generation and manipulation of spin-carrying supercurrents. In this video we will introduce the concept of superconducting spin-electronics and illustrate two different strategies to create non-dissipative supercurrents in superconductor-ferromagnet hybrid nanostructures.
