“…The polycrystalline samples were prepared by arc melting stoichiometric amounts of the pure metals components. Starting materials were used in the form of 4N Pd pellet, 5N Al wire as supplied by A. D. Mackay Inc. and 99.85 % Am metal( 243 Am isotope [20]) produced originally by thermo reduction process [21] with 3N purity. Other actinides (Np, Pu) are present at ppm level [22] in Am after long term storage (∼10 years).…”

We report on the crystal structure, magnetic susceptibility, specific heat, electrical and thermoelectrical properties of AmPd5Al2, the americium counterpart of the unconventional superconductor NpPd5Al2. AmPd5Al2 crystallizes in the ZrNi2Al5-type of structure with lattice parameters: a = 4.1298 Å and c = 14.7925 Å. Magnetic measurements of AmPd5Al2 indicate a paramagnetic behavior with no hint of magnetic ordering nor superconductivity down to 2 K. This aspect is directly related to its 5f 6 electronic configuration with J = 0. The specific heat measurements confirm the non magnetic ground state of this compound. The low temperature electronic specific heat γe ∼ 20 mJ mol −1 K −2 is clearly enhanced as compared to americium metal. All transport measurements obtained point to a metallic behavior in AmPd5Al2.
