Kondo Anomalies of the Heavy Fermion Systems**Project Supported by National Natural Science Foundation of China

Abstract

The interdependences of the low temperature properties in heavy fermion compounds with the Kondo lattice parameters are obtained from a two-conduction band periodic exchange model by using the Green's function method .The results indicate that the anomalous low temperature properties of the specific heat, resistivity and the static magnetic susceptibility in the heavy fermion systems are all the characteristic features of the kondo lattice. The influences of the pressure on the Kondo temperature TX and on the superconducting transition temperature TC in the heavy fermion systems are also discussed.
