Abstract

Magnetic field-induced superconductivity is a fascinating quantum phenomenon, whose origin is yet to be fully understood. The recently discovered spin-triplet superconductor, UTe 2, exhibits two such superconducting phases, with the second one reentering in the magnetic field of 45 T and persisting up to 65 T. More surprisingly, in order to induce this superconducting phase, the magnetic field has to be applied in a special angle range, not along any high symmetry crystalline direction. Here we investigated the evolution of this high-field-induced superconducting phase under pressure. Two superconducting phases merge together under pressure, and the zero resistance persists up to 45 T, the field limit of the current study. We also reveal that the high-field-induced superconducting phase is completely decoupled from the first-order field-polarized phase transition, different from the previously known example of field-induced superconductivity in URhGe, indicating superconductivity boosted by a different paring mechanism.

  • This stabilization regime would, if accurate, indicate the existence of an even higher field phase beyond SCFP, located at approximately 90 T, and that the quantum limit field has somehow been lowered from the H > 100 T region inferred from recently reported quantum oscillation frequencies.

    “This stabilization regime would, if accurate, indicate the existence of an even higher field phase beyond SCFP, located at approximately 90 T22,62, and moreover that the quantum limit field has somehow been lowered from the H > 100 T region inferred from recently reported59,60 quantum oscillation frequencies.”

  • UTe2 does not magnetically order below 1.4 GPa.

    “While other uranium-containing superconductors, such as URhGe26 and UCoGe1, exhibit field stabilized reentrant superconductivity at specific angles, these phases occur in proximity to ferromagnetic quantum critical points, whereas UTe2 does not magnetically order below 1.4 GPa22.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
