Superconducting critical temperature elevated by intense magnetic fields
Original language description
Below a critical temperature Tc, superconductors transport electrical charge without dissipative energy losses. The application of a magnetic field B generally acts to suppress Tc, up to some critical field strength at which Tc RIGHTWARDS ARROW 0 K. Here, we investigate magnetic field-induced superconductivity in high-quality specimens of the triplet superconductor candidate UTe2 in pulsed magnetic fields up to B = 70 T. Strikingly, we find that this material has a higher Tc when B > 40 T (Tc ALMOST EQUAL TO 2.4 K) than it does for B = 0 T (Tc = 2.1 K). This observation points to a fundamentally distinct mechanism for the formation of superconductivity at high B in UTe2 compared to the case of B = 0 T.
