|Abstract:||A new phase PuPdSn was prepared and studied by X-ray diffraction, magnetization and heat capacity measurements, performed in the temperature range 2¿300 K and in magnetic fields up to 14 T. The crystal structure determined from single-crystal X-ray data is the hexagonal ZrNiAl-type [space group ] with lattice parameters: a = 7.5057 Å and c = 4.0853 Å. PuPdSn orders antiferromagnetically at TN = 21 K. Moreover, another antiferromagnetic-like transition takes place at 9.6 K. Above TN the susceptibility follows a modified Curie¿Weiss law with µeff = 1.0 µB, Tp = -14 K and¿0 = 2.1 × 10-4 emu/mol. The low-temperature linear specific heat coefficient is small (¿ 8 mJ/mol K2) pointing to well localized 5f electrons|
