In a groundbreaking advancement, researchers at The University of Manchester have successfully achieved robust superconductivity in high magnetic fields using a novel one-dimensional (1D) system. Superconductivity, the phenomenon that enables certain materials to conduct electricity with zero resistance, holds immense potential for quantum technology advancements.
Inspired by their earlier work demonstrating that boundaries between domains in graphene could be highly conductive, the research team led by Professor Andre Geim, Dr. Julien Barrier, and Dr. Na Xin devised a novel strategy. By placing domain walls between two superconductors, they were able to achieve the ultimate proximity between counterpropagating edge states while minimizing the effects of disorder. This innovative approach enabled them to observe large supercurrents at relatively “mild” temperatures up to 1 Kelvin in every device they fabricated.
