Abstract Reentrant superconductivity is an uncommon phenomenon in which the destructive effects of Storage Shelf magnetic field on superconductivity are mitigated, allowing a zero-resistance state to survive under conditions that would otherwise destroy it.Typically, the reentrant superconducting region derives from a zero-field parent superconducting phase.Here, we show that in UTe2 crystals extreme applied magnetic fields give rise to an unprecedented high-field superconductor that lacks a zero-field antecedent.This high-field orphan superconductivity exists at angles offset between 29o and 42o from the Circle Pendant With Birthstone Beads Necklace Premium Box crystallographic b to c axes with applied fields between 37 T and 52 T.

The stability of field-induced orphan superconductivity presented in this work defies both empirical precedent and theoretical explanation and demonstrates that high-field superconductivity can exist in an otherwise non-superconducting material.
