Abstract

The occurrence of a maximum at a temperature T_max in the resistivity of the dense Kondo compound CeNiAl₄ and in (Ce_1-xY _x)NiAl₄ alloys is investigated. T_max (∝ T_K, the Kondo temperature) first increases, goes through a maximum value and decreases with increase in x. This behaviour is qualitatively explained by considering the competing influence of volume changes and dilution (the Kondo-hole effect) on the Kondo system. Complementary magnetic susceptibility measurements corroborate these results.
