We have carried out115In nuclear quadrupole resonance (NQR) measurements in CeRhIn5 and CeCoIn5 under presure P. The nuclear spin-lattice relaxation rates; 1/T1; of115In indicated that the anisotropic superconductivity with line nodes occurred near an antiferromagnetic state. The application of P suppressed the antiferromagnetic; AF; spin fluctuations and moves the system away from the AF state to the non-magnetic Fermi liquid state. The P dependence of 1/T1 in the superconducting state of CeCoIn5 shows that the magnitude of the superconducting energy gap scales with its TC up to 3.0 GPa. © 2005 Elsevier B.V.
