Magnetic and transport studies on Ce(Pd1-xCux)3 alloys — •Mahboubeh Houshiar — Shahid Beheshti University, Tehran, Iran

The system of compounds Ce(Pd1-xCux)3 with ( x = 0, 0.017, 0.033 and 0.133 ) crystallize in the cubic AuCu3 - type structure with copper entering the lattice in substitution for Pd. With increasing copper content they show temperature shifts in max resistivity and TEPmax, but for higher concentration the maximum disappears. The susceptibility shows a large reduction in the paramagnetic Curie temperature with increasing x which indicate rapid decrease of the Kondo temperature with increasing copper content.
