Abstract

We discuss (i) UPd₂Al₃, for which local-moment antiferromagnetism (T_N = 14.3 K) coexists with heavy-fermion (HF) superconductivity below T_c ∼ 2 K, (ii) the HF superconductor CeCu₂Si₂ (T_c ≈ 0.6 K) which, for B > B_c2, shows pronounced "non-Fermi-liquid" (NFL) effects near a quantum-critical point at which the spin-density-wave "phase A" disappears, and (iii) the NFL CeNi₂Ge₂, a "clean-limit" HF superconductor below T_c ≈ 0.1 K.
