Abstract
Cerium is in a mixed valent state in CePd3 (AuCu3 type structure) while it is in a trivalent state in CePt3 (defect C15 Laves type structure). CePd3−xPtx alloys have been prepared and are found to have AuCu3 type structure for 0 ≤ x ≤ 1 and defect Laves type structure for 1.75 < x ≤ 3.0. From susceptibility measurements on these alloys in the temperature range 77-400 K, it is inferred that cerium is in a mixed valent state in all the AuCu3 type alloys, but in a trivalent state in all the Laves phase type alloys in CePd3−xPtx series.
