Résumé

Among the 10 phases reported to exist at 973 K in the Ce-Co-Ge ternary system, a strong dependence of the magnetic and transport properties on the constituent concentration has been evidenced. Close to the Ce-Ge binary axis, the ternary phases exhibit ferromagnetic-like ordering with low TC, while increasing the cobalt concentration leads first to a paramagnetic area, then to an antiferromagnetic one and finally to ferromagnetism with high TC for cobalt and Co-rich binaries. Similarly, electrical resistivity and thermopower measurements evidence a rather metallic behavior for cerium poor phases while an increase in the Ce-content results in an increase of the Kondo-like interactions.
