Abstract
Some of the outstanding and newly discovered features of heavy-electron systems are reviewed. Unconventional superconductivity, small-moment ordering, and possible non-Fermi-liquid behaviour are the most intriguing properties that deserve further experimental and theoretical studies because they touch upon important questions related with strong many-body effects in general. Possible ground states of these systems are strongly influenced by small variations of chemical composition or by mere lattice defects.
