Abstract
We report evidence for unconventional superconductivity in CeIn3 at a pressure P=2.65 GPa above the critical pressure (Pc∼2.5 GPa) revealed by measurements of the nuclear-spin-lattice-relaxation time (T1) and ac susceptibility (ac-χ). Both measurements of T1 and ac-χ have pointed to a superconducting transition at Tc=95 mK, which is much lower than the onset temperature Tonset=0.15 K at zero resistance. The temperature dependence of 1/T1 shows no coherence peak just below Tc, indicative of an unconventional nature for the superconductivity induced in CeIn3.
