Zero field In Nuclear Quadrupole Resonance (NQR) measurements at ambient pressure have been carried out on a single crystal of CePtIn, a heavy fermion compound exhibiting two magnetic transitions at T1 = 2.2 K and TN = 2 K prior to entering a superconducting state below Tc =0.32 K.

Recently, Ran et al. reported evidence for superconductivity in the uranium-based heavy fermion material UTe, exhibiting the rather high transition temperature of 1.6 K. The ground state of UTe is paramagnetic, not ferromagnetic. However, the compound still exhibits a very large and anisotropic upper critical field H
, exceeding the Pauli limit along the three principal axes, similar to the ferromagnetic superconductors, UCoGe and URhGe. Field-induced metamagnetic transition and re-entrant superconducting behaviour have been reported under strong magnetic fields around 35 T, when a magnetic field was applied along the orthorhombic hard-magnetization b-axis. In this study, we have performed Te-NMR measurements on a newly discovered heavy fermion superconductor UTe. Our NMR data confirm a moderate Ising anisotropy for both the static (K) and dynamical susceptibilities (1/
) in the paramagnetic state above about 20 K.
