Abstract

We succeeded in growing single crystals of UPd₂Cd₂₀ by the Cd self-flux method. This compound crystallizes in the cubic CeCr₂Al₂₀-type structure. From the low-temperature electrical resistivity and Kadowaki-Woods relation, the electronic specific heat coefficient γ is estimated to be about 400mJ/mol ·K². The magnetic susceptibility of UPd₂Cd₂₀ indicates a broad max-imum at 6.6K and a rapid decrease at 5.0K, which correspond to the formation of the heavy fermion state and the antiferromagnetic transition, respectively. These experimental results strongly suggest that UPd₂Cd₂₀ is a new heavy fermion antiferromagnet.
