Novel Types of Superconductivity in F‐Electron Systems

MAR 01, 1986

Compounds of rare earth and actinide elements with partially filled f‐electron shells show superconductivity induced by magnetic fields, carried by “heavy” electrons and destroyed below a second critical temperature.

During the last one and one‐half decades, experiments on compounds and alloys of rare earth and actinide elements with partially filled f‐electron shells have revealed novel superconducting phenomena. Among these are the reappearance of resistance at a second critical temperature due to the interaction of magnetic moments with conduction electrons, the coexistence of superconductivity and antiferromagnetism, superconductivity induced by magnetic fields and superconductivity due to electrons with large effective masses.
