Description

We report the discovery of new superconducting and novel magnetic phases in CeIn3 on the verge of antiferromagnetism (AFM) under pressure (P) through the In-nuclear quadrupole resonance (NQR) measurements. We have found a P-induced phase separation of AFM and paramagnetism (PM) without any trace of a quantum phase transition in CeIn3. A new type of superconductivity (SC) was found, under P=2.28–2.5 GPa, to coexist with AFM. It is magnetically separated from PM where the heavy fermion SC takes place. We propose that the magnetic excitations such as spin-density fluctuations induced by the first-order magnetic phase transition might mediate attractive interaction to form Cooper pairs.
