Investigations of magnetic, transport and thermodynamic properties of RE 8 Pd 24 In (RE=Pr, Nd, Gd, Tb, Dy, Ho, Er and Tm) are reported through measurements of X-ray diffraction, electrical resistivity (ρ(T)), magnetic susceptibility (χ(T)), magnetization (σ(μ0H)) and heat capacity (Cp(T)). These ternary compounds have the cubic AuCu 3 -type structure. Compounds with RE=Gd and Tb order antiferromagnetically (AF) and exhibit magnetic transitions observed in their χ(T) and Cp(T). ρ(T) results for the Gd and Tb compounds indicate a minimum above the magnetic phase transition temperature TN, and an increase in ρ(T) upon further cooling as a precursor of AF order at lower temperatures. χ(T) data at high temperatures follow the Curie–Weiss relation for all compounds and give effective moment values close to those expected for the free RE 3+ -ion. Enhanced values of the electronic contribution to the heat capacity were observed for Gd 8 Pd 24 In and Tb 8 Pd 24 In.
