We review the current NMR/NQR studies on superconducting and magnetic phases close to the magnetic instability under pressure (P) in heavy-fermion (HF) systems. In this article, by means of NQR studies, we highlight the novel phase diagrams of magnetism and superconductivity (SC) in the HF antiferromagnets CeCu2Si2, CeRhIn5, CeIn 3, and the itinerant ferromagnet UGe2. A new light is shed on the difference and common features on the interplay between magnetism and SC.
