Uranium-kristal hervindt supergeleiding bij extreem sterk magneetveld

Austrian scientists have identified why uranium ditelluride (UTe2), a uranium-based superconductor smaller than a grain of sand, regains superconductivity at extremely high magnetic fields between 40 and 70 Tesla after losing it at lower fields around 10 Tesla. This unusual "reentrant superconductivity" defies conventional physics, as strong magnetic fields typically destroy superconductivity. Researchers at the Institute of Science and Technology Austria discovered that despite UTe2 not being magnetic itself, it exhibits this exceptional behavior through mechanisms they are now beginning to
