Superconducting critical temperature elevated by intense magnetic fields.

Below a critical temperature [Formula: see text], superconductors transport electrical charge without dissipative energy losses. The application of a magnetic field [Formula: see text] generally acts to suppress [Formula: see text], up to some critical field strength at which [Formula: see text] 0 K. Here, we investigate magnetic field-induced superconductivity in high-quality specimens of the triplet superconductor candidate UTe[Formula: see text] in pulsed magnetic fields up to [Formula: see text] [Formula: see text] 70 T. Strikingly, we find that this material has a higher [Formula: see text] when [Formula: see text] 40 T ([Formula: see text] 2.4 K) than it does for [Formula: see text] 0 T ([Formula: see text] 2.1 K). This observation points to a fundamentally distinct mechanism for the formation of superconductivity at high [Formula: see text] in UTe[Formula: see text] compared to the case of [Formula: see text] [Formula: see text] 0 T.
