WEAK KONDO INTERACTION IN CE(M(X)GA(1-X))(4) ALLOYS, M=AG AND AU

The crystal structure of the title compounds has been characterized by quantitative room-temperature X-ray powder diffraction to be isotypic with the BaAl4 type with partial disorder among the p-metal atoms. Th e low-temperature behaviour of these alloys is characterized by a decr ease of the ordering temperatures as the Au content increases. Weak Ko ndo interaction for alloys richest in Au is observed from various tran sport and specific heat measurements.
