Chapter 11 Kondo effect: Alloys and compounds

摘要: Publisher Summary The chapter discusses the Kondo effect. interaction between impurity ions with partially filled d or f electron shells and conduction electrons of a metallic host can lead to variations in certain physical properties temperature magnetic field that have come be associated “Kondo effect.” In zero field, these dependent anomalies scale characteristic TK, temperature, above which matrix system behaves magnetically below matrix-impurity nonmagnetically. exhibit attributable effect include electrical resistivity, susceptibility, thermoelectric power, specific heat; and, systems where appropriate, superconducting such as critical Tc jump heat occurs at Tc. Because wide range character displayed by lanthanide reviewed chapter, they provide rich testing ground for concepts theories been advanced account Kondo-like systems. briefly number models, proposed describe behavior their properties.
