Abstract

Electrical resistivity and the magnetic susceptibility have been measured for the series of intermetallic compounds CeCo_xNi _1-xGe₂(x = 0.1, 0.2, 0.5, 0.7, 0.8, 0.9 and 1). CeNiGe₂ is an antiferromagnetic compound with T_N = 3.3 K. CeCoGe₂ is an intermediate-valence compound with cerium valence varying from 3.2 at room temperature to 3.8 at 1.8 K. The valence fluctuations are quenched at x = 0.5, while the heavy Fermion behavior appears in compositions with x<0.5.
