One-atom-high rails steer superconducting vortices, with temperature and magnetic field tuning their guidance
Researchers at the Research Center for Materials Nanoarchitectonics (MANA), a center within Japan's National Institute for Materials Science (NIMS), discovered that atomic-scale steps can guide superconducting vortices in an ultrathin superconductor.
