Abstract

We report on the pressure (P)-induced phase diagram of antiferromagnetism (AFM) and superconductivity (SC) which emerges at their border at zero magnetic field. The nuclear-quadrupole-resonance (NQR) measurements have revealed that AFM can take place in the superconducting state with Tc ∼ 2.1 K at P = 2.05 GPa. The present experiments have, for the first time, demonstrated that AFM phase, AFM + SC uniformly coexisting phase, SC phase and paramagnetic phase all contact with each other at Ttetra ∼ 2.1 K and Ptetra ∼ 2 GPa which evidence the existence of the tetracritical point in the P-T phase diagram of AFM and SC in CeRnIn5.
