Abstract: A new compound NpPdSn was prepared and studied by X-ray di®raction, magnetization, heat capacity and electrical resistivity measurements, performed in the temperature range 2{300 K and under magnetic ¯eld up to 14 T. The crystal structure determined by single-crystal X-ray analysis is hexagonal with ZrNiAl-type (space group P62m). NpPdSn orders antiferromagnetically at 19 K and exhibits a Curie{Weiss behavior with ¹e® = 2:66 ¹B and £p = ¡47 K. Bulk properties show temperature variations similar to systems with strong electronic correlations with a large negative paramagnetic Curie temperature and an enhanced low-temperature speci¯c heat (° ¼ 90 mJ/(mol K2)). It suggests that NpPdSn may be classi¯ed as a new Np-based antiferromagnetic Kondo lattice, one of the very few known amidst transuranium-based intermetallics.
