"Halo" Superconductivity Mapped
The "resurrection" of superconductivity in uranium ditelluride at extremely high magnetic fields, initially identified by researchers at the University of Maryland Quantum Materials Center and the National Institute of Standards and Technology (NIST), has captivated physicists worldwide. In UTe2, superconductivity vanishes below 10 Tesla, but surprisingly reemerges at field strengths exceeding 40 Tesla. Led by NIST NRC Fellow and QMC member Sylvia Lewin, measurements at the National High Magnetic Field Laboratory have revealed a three-dimensional superconducting halo that wraps around the hard b-axis of the crystal, as outlined Science.
