Recent work on strongly correlated electron systems realized in heavy‐fermion (HF) metals is reviewed. Particular emphasis is put on different types of antiferromagnetic quantum critical points (QCPs). HF superconductivity seems to be favored only in the presence of a QCP of conventional (spin‐density‐wave) rather than of unconventional nature. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
