Symmetry of magnetic correlations in spin-triplet superconductor UTe₂

Uranium ditelluride UTe₂ is an unusual low-temperature superconductor that is a leading candidate for the realization of spin-triplet pairing and shows signs of multiple order parameters, time-reversal symmetry breaking, and in-gap chiral surface states. Moreover, UTe₂ also hosts several high-field reentrant superconducting phases. An outstanding question is what role magnetic interactions play in this system, especially with regard to the superconducting pairing. In this talk, I will describe neutron scattering results and what they tell us about electron hybridization, magnetic interactions, and ramifications for superconductivity.
