Magnetic excitation spectra of the candidate spin-triplet superconductor UTe2 investigated by inelastic neutron scattering

ORAL

Abstract

Enormous attention has been attracted recently by UTe2 due to its potential for realizing spin-triplet superconductivity. What little is known regarding the underlying magnetic interactions and excitations is gathered from previous inelastic neutron scattering studies. We present the results of a recent neutron study performed on a mosaic of single crystalline samples of superconducting UTe2. The magnetism in UTe2 is likely key to the formation of its exotic spin-triplet superconducting ground state, thus its magnetic excitations, as measured by this experiment, are informative in the context of phenomena related to the correlated electron effects such as Kondo hybridization.
