Phenomenological Relationships in Heavy Fermi Liquids
Summary Trends for the occurrence of superconductivity .and magnetic order in narrow-band metals are reviewed. Magnetic interactions and strongly nonadiabatic coupling between electrons and the lattice are discussed as important limitations on the superconducting transition temperature. Numerous similarities in the physical properties of high-Tc superconductors, valence fluctuation and heavy fermion materials are summarized. The strong influence of the magnetoresistance in upper critical field behavior, and “T2 dependences” of the heat capacity are proposed as novel characteristics of heavy fermion systems.
