Superconductivity: Controlling magnetism

Manipulation of the magnetic state in spin valve structures by superconductivity has now been achieved, opening a new route for the development of ultra-fast cryogenic memories. Spintronics is a rapidly developing field that allows insight into fundamental spin-dependent physical properties and the development of practical applications, such as the read head sensors for hard drives in computers. superconducting spintronics, which involves structures formed by ferromagnetic (FM) and superconducting (SC) layers, has emerged, promising advances in the fundamental understanding of the competition between superconducting and magnetic ordering, as well as new device functionalities.
