Magnetic signatures of multicomponent superconductivity in pressurized UTe2

The heavy fermion material UTe$_2$ possesses a rich phase diagram with multiple superconducting phases, several of which exhibit characteristics of odd-parity pairing. Here, we report on the pressure dependence of signatures of the superconducting transition in the temperature dependent ac magnetic...

Zusammenfassung:The heavy fermion material UTe$_2$ possesses a rich phase diagram with multiple superconducting phases, several of which exhibit characteristics of odd-parity pairing. Here, we report on the pressure dependence of signatures of the superconducting transition in the temperature dependent ac magnetic susceptibility $\chi(T)$ in high quality UTe$_2$ single crystals. We resolve a single superconducting transition in $\chi(T)$ at low pressures $
