Researchers recently realized the first de Gennes' superconducting switch where superconductivity is completely suppressed. Credit: University of Jyväskylä The University of Jyväskylä, Finland, has been involved as part of an international collaboration that has identified a way to completely suppress superconductivity in superconducting and ferromagnetic junctions. The results published in Nature Communications are key to the development of non-volatile superconducting random access memories an...
