Abstract

We report a novel pressure(P)-induced evolution on the magnetism in the P-induced superconductor CeRhlns revealed by measurements of the 115 In nuclear-spin-lattice-relaxation rate (1151/Ti). In the itinerant antiferromagnet CeRhln5 with the Néel temperature Tn = 3.8 K at P=0, Tn begins to be reduced to Tn = 3.6 K at P = 1.23 GPa that is close to the border of the superconducting phase. An emergent behavior is the observation of a pseudogap behavior that is revealed by a broad peak in the temperature dependence of 1/T1T at P = 1.23 GPa. With further increasing P up to P = 2.1 GPa where its bulk superconductivity is fully established, the pseudogap behavior is not seen in the normal state. The insensitive P dependence of Tc in CeRhln5 is suggested to be related to that of the characteristic temperature T which marks a localized to itinerant magnetic crossover.
