Abstract

The electrical resistivity and the magnetic susceptibility have been measured for the series of intermetallic compounds CeNiGe_2-xSi _x. CeNiGe₂ is an antiferromagnetic compound with T _N = 3.3 K. CeNiSi₂ is an intermediate-valence compound with cerium valence varying from 3.4 at room temperature to 3.75 at 1.8 K. With increasing x, the coupling constant J is enhanced and thus the Kondo temperature T_K increases.
