Abstract The recently discovered heavy-fermion spin-triplet superconductor candidate UTe2 provides a rich platform for unconventional pairing and topological phenomena. However, limited has been known about its superconducting order parameters and their evolution with control parameters, largely due to the lack of appropriate symmetry-sensitive detection methods. Here, we report comprehensive point-contact spectroscopy measurements of pressurized UTe2 on the (0 0 1) surface.

1 Introduction Single-molecule magnets (SMMs), a special class of molecule-based magnets in which nanomagnetic units are isolated by organic ligands, have drawn widespread attention for their potential applications in high-density spintronic devices[1] and quantum computing[2, 3] in the past two decades. SMMs are characterized by slow magnetic relaxation below a magnetic blocking temperature and unique resonant quantum tunneling of magnetization (RQTM)[4] at low temperatures.
