Scientists create nano-patterned superconducting thin films

A team of scientists from Bar-Ilan University, Israel, and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has fabricated thin films patterned with large arrays of nanowires and loops that are superconducting - able to carry electric current with no resistance - when cooled below about 30 kelvin (-243 degrees Celsius). Even more interesting, the scientists showed they could change the material's electrical resistance in an unexpected way by placing the material in an external magnetic field...
