superconducting diodes

MIT scientists and colleagues have created a superconducting device that could dramatically cut energy use in computing, among other important applications. In one design the diode consists of a ferromagnetic strip (pink) atop a superconducting thin film (grey). The team also identified the key factors behind the resulting current that travels in only one direction with no resistance.Credit: A. Varambally, Y-S. Hou and H. Chi Team creates simple
