Description We report here our results showing the occurrence of magnetic order in the intermetallic compounds NdCu2Sn2 and PrCu2Sn2. For comparison, non-magnetic analogue, LaCu2Sn2, was also prepared. X-ray diffraction (XRD) result confirms that all the three compounds form in the tetragonal CaBe2Ge2-type structure. A cusp is observed at not, vert, similar3 K in the magnetic susceptibility of NdCu2Sn2 and PrCu2Sn2, which arises due to the antiferromagnetic ordering of the magnetic moments in these two compounds. The bulk nature of magnetic order in both the compounds is confirmed from the observation of peaks in the heat capacity at the magnetic transition temperature. X-ray absorption measurements at the LIII edge show that Pr ions are in the trivalent state in PrCu2Sn2.
