Title: Nearly ferromagnetic spin-triplet superconductivity

Abstract

Spin-triplet superconductors potentially host topological excitations that are of interest for quantum information processing. We report the discovery of spin-triplet superconductivity in UTe 2, featuring a transition temperature of 1.6 kelvin and a very large and anisotropic upper critical field exceeding 40 teslas. This superconducting phase stability suggests that UTe 2is related to ferromagnetic superconductors such as UGe 2, URhGe, and UCoGe. However, the lack of magnetic order and the observation of quantum critical scaling place UTe 2at the paramagnetic end of this ferromagnetic superconductor series. A large intrinsic zero-temperature reservoir of ungapped fermions indicates a highly unconventional type of superconducting pairing.
