Abstract

We report on the magnetic properties of single crystals of U₃Pd₂₀Si₆ which crystallizes in the cubic C₆Cr₂₃-type structure with U being located on two different crystallographic sites. The electrical resistivity shows a metallic behavior at higher temperatures and two successive magnetic phase transitions are found in the specific heat and the magnetic susceptibility at 19 and 2 K. The temperature dependence of susceptibility obeys the Curie-Weiss law above about 50 K with an effective moment 3.30 μ_B/U. Magnetic entropy reaches Rln3 per uranium ion at 19 K. These results suggests that U₃Pd₂₀Si₆ is a typical localized 5f electron system and a rare metallic uranium compound.
