Superconductivity is usually thought to be inherently fragile towards the application of magnetic fields. Here we show that in the new topological superconductor UTe2, which has a critical temperature of only 1.6 K, a magnetic field applied along a specific crystal axis leads to a pronounced reinforcement of superconductivity, which survives up to almost 35 T. Even more astonishing, a new superconducting phase appears for fields above 45 T and a field direction slightly away from this axis.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
