Burnell Though superconductivity and ferromagnetism are traditionally seen as competing phenomena, when representative materials are artificially juxtaposed, a trove of unusual physics is found at the interface. For example, in a Nb/Er bilayer, adjusting the magnetic state of the Er at remanence changes the shape of the resistivity transition in the Nb, controlling its superconducting T c . Thus the Nb “remembers” the field applied to the Er, which could be the basis of energy-efficient data storage in cryogenic s u p e r c o n d u c t i n g s p i n t r o n i c s . [Phys. Rev.
