| Abstract: | Single crystals of Tb4MGa12 (M=Pd, Pt) have been synthesized. The isostructural compounds crystallize in the cubic space group  , with Z=2 and lattice parameters: a=8.5940(5) and 8.5850(3) Å for Tb4PdGa12 and Tb4PtGa12, respectively. The crystal structure consists of corner-sharing MGa6 octahedra and TbGa3 cuboctahedra. Magnetic measurements suggest that Tb4PdGa12 is an antiferromagnetic metamagnet with a Néel temperature of 16 K, while the Pt analog orders at TN=12 K. |
