Abstract
We report on an investigation of superconductivity and magnetism in the series of compounds M${\mathrm{Pd}}_{2}$Pb (M=rare earth, Th, U) through measurements of electrical resistivity, magnetic susceptibility, specific heat, and lattice parameters. Both single crystals and polycrystalline samples were studied. The compound ${\mathrm{UPd}}_{2}$Pb was examined for possible heavy-fermion behavior, and found to exhibit antiferromagnetic order below T=35 K. \textcopyright{} 1996 The American Physical Society.
