Abstract

We report 115In nuclear-quadrupole-resonance (NQR) measurements of the pressure(P)-induced superconductor CeRhIn5 in the antiferromagnetic (AF) and superconducting (SC) states. In the AF region, the internal field at the In site is substantially reduced from 1.75 kOe at P = 0 to 0.39 kOe at P = 1.23 GPa, while TN slightly changes with increasing P. This suggests that either the size or the direction of the ordered moment changes as P increases. In the SC state at P = 2.1 GPa, the nuclear spin-lattice relaxation rate has revealed a T3 dependence without the coherence peak just below Tc, giving evidence for the unconventional superconductivity.
