The systematic measurements of ac susceptibility, nuclear-quadrupole-resonance spectrum and nuclear-spin-lattice-relaxation time (T1) on the pressure (P)-induced heavy-fermion superconductor CeRhIn5 were reported. The temperature (T) dependence of 1/T 1 at P = 1.6 GPa has revealed that antiferromagnetism (AFM) and superconductivity (SC) coexist microscopically, exhibiting the respective transition at TN=2.8 K and TcMF = 0.9 K. It was demonstrated that SC does not yield and trace of gap opening in low-lying excitations below Tconset = 2 K.
