  Neutron diffraction results for CePt2+x alloys with 0 less than or equal to x less than or equal to 1, combined with low resolution room temperature x-ray diffraction and electron microscopy, confirm that the alloys are single phase. The data dan be fit for all x with nearly equal agreement factors by structural refinements in either the C15 (MgCu2) phase br the C15b (AuBe5) structure. Observation of small peaks in the diffraction pattern for CePt, that are forbidden in C15 suggest that C15b is the correct structure for this composition (and possibly for the other alloy compositions); and application of Hamilton's test indicates that the C15b structure is preferred over the C15 to the 95% confidence level. Magnetic susceptibility and specific heat measurements indicate that the cerium is essentially localized and trivalent for all x. The antiferromagnetism observed for CePt, may be absent in the alloys, which behave as typical nonmagnetic cerium heavy fermion compounds with Kondo temperature T-K approximate to 2 K.

  CePt2 is an antiferromagnetic (AF) Kondo-lattice compound with T-N similar to 1.7K and T-K similar to 4.6K. The evolution of AF and Kondo interactions in CePt2+x with x = 0,0.5 and 1 is observed by analysis of the temperature-dependent specific heat. This analysis shows that similar to 56% of the Ce in CePt2 is involved in Kondo interactions, with the rest involved in magnetic correlations. While 100% of the expected entropy (R ln2) is recovered by 15 K in CePt2, only 95% and 93% is recovered for x = 0.5 and 1.0, respectively. Meanwhile a larger Kondo fraction (80-90%) and a smaller AF fraction (15-3%) is observed, while T-K decreases from 4.6 K to 2.8 K as x increases from 0 to 1. This trend in T-K is opposite that expected from the measured lattice contraction. We conjecture that lattice disorder induced by Pt alloying is responsible for these results. (c) 2006 Elsevier B.V..
