Abstract

The specific heat in low temperature regions was measured for several pseudoternary compounds of the CeNiGe_2-xSi_x system. Substitution of silicon for germanium enhances the coupling constant J and the Kondo interaction. The antiferromagnetism in CeNiGe₂ is ultimately suppressed around x = 1 by the enhanced Kondo effect. A non-Fermi liquid behavior has been observed in x = 1 composition.
