Pressure-Temperature Phase Diagram of Antiferromagnetism and Superconductivity in CeRhIn5 and CeIn3 : In-NQR Study under Pressure

Abstract

We report the novel pressure($P$) - temperature($T$) phase diagram of antiferromagnetism and superconductivity in CeRhIn${}_5$ and CeIn${}_3$ revealed by the ${}^{115}$In nuclear-spin-lattice-relaxation ($T_1$) measurement. In the itinerant magnet CeRhIn${}_5$, we found that the Néel temperature $T_N$ is reduced at $P\ge$ 1.23 GPa with an emergent pseudogap behavior. In CeIn${}_3$, the localized magnetic character is robust against the application of pressure up to $P\sim$ 1.9 GPa, beyond which the system evolves into an itinerant regime in which the resistive superconducting phase emerges. We discuss the relationship between the phase diagram and the magnetic fluctuations.
