(TbPd3)8T (T=Ga and Ge) compounds have the cubic, Pm3m symmetry and are a superstructure derivative of the cubic, AuCu3-type, TbPd3. The ternary compounds order antiferromagnetically and the Néel temperature is different from the binary compound TbPd3, which has an antiferromagnetic ordering at 3 K. Two transitions are observed in (TbPd3)8Ge, one at 4 K and the other at 5.2 K. The compound (TbPd3)8Ga has an antiferromagnetic ordering at 5.2 K. The resistivity exhibits hysteresis in the transition regime in both compounds. The magnetic transitions are first-order like and sharp metamagnetic transition is observed below the magnetic ordering temperature in both (TbPd3)8Ga and (TbPd3)8Ge. © 2000 American Institute of Physics.
