We review the studies on the emergent phases of superconductvity and magnetism in the f-electron derived heavy-fermion (HF) systems by means of the nuclear-quadrupole-resonance (NQR) under pressure. These studies have unraveled a rich variety of the phenomena in the ground state of HF systems. In this article, we highlight the novel phase diagrams of magnetism and unconventional superconductivity (SC) in CeCu 2Si 2, HF antiferromagnets CeRhIn 5, and CeIn 3. A new light is shed on the difference and common features on the interplay between magnetism and SC on the magnetic criticality.
