Abstract
We discuss (i) UPd2Al3, for which local-moment antiferromagnetism (T-N = 14 .3 K) coexists with heavy-fermion (HF) superconductivity below T-c approxim ate to 2 K, (ii) the HF superconductor CeCu2Si2 (T-c approximate to 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" disappea rs, and (iii) the NFL CeNi2Ge2, a "clean-limit" BF superconductor below T-c approximate to 0.1 K.
