SUPERCONDUCTIVITY IN RARE-EARTH AND ACTINIDE COMPOUNDS

Rare earth and actinide compounds and the extraordinary superconductin g and magnetic phenomena they exhibit are surveyed. The rare earth and actinide compounds described belong to three classes of novel superco nducting materials: high temperature, high field superconductors (inte rmetallics and layered cuprates); superconductors containing localized magnetic moments; heavy fermion superconductors. Recent experiments o n the resistive upper critical field of high T-c cuprate superconducto rs and the peak effect in the critical current density of the f-electr on superconductor CeRu2 are discussed.
