Magnetic field-induced superconductivity is a fascinating quantum phenomenon, whose origin is yet to be fully understood. The recently discovered spin-triplet superconductor, UTe₂, 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.

磁场诱导超导是一种迷人的量子现象，其起源尚未完全了解。最近发现的自旋三重态超导体 UTe ₂，表现出两个这样的超导相，第二个重新进入 45 T 的磁场并持续到 65 T。更令人惊讶的是，为了诱导这种超导相，必须在特殊的角度范围内施加磁场，不沿任何高度对称的结晶方向。在这里，我们研究了这种高场诱导超导相在压力下的演变。两个超导相在压力下融合在一起，零电阻持续到 45 T，这是当前研究的场极限。我们还揭示了高场致超导相与一阶场极化相变完全解耦，这与之前已知的 URhGe 场致超导示例不同，表明超导性由不同的配对机制增强。
