Abstract
We report on pressure-induced evolutions of antiferromagnetic spin fluctuations (AFM-SFs) and unconventional superconductivity on the x = 0.6 sample in a series of compounds CeRh1 - x Irx In5 via the 115In nuclear-quadrupole-resonance (NQR) experiment. The In-NQR 1 / T1 measurements have revealed that the slight application of pressure makes Tc = 0.9 K at P = 0 increase up to Tc = 1.06 K at P = 0.47 GPa. Concomitantly, the character of AFM-SF evolves from an isotropic regime to an anisotropic one as P increases. These results suggest that AFM-SFs play vital role in mediating the strong-coupling superconductivity in CeRh1 - x Irx In5.
