Abstract

Two new ternary compounds of the composition RCo₃Ga₂ (R = Tb, Y) have been prepared and identified by X-ray diffraction. The compounds crystallize in a new hexagonal structure, forming a 'superlattice' with lattice vectors, a and b, that are larger by a factor of √3 compared with the unit cell of the related pseudobinary compound RCo_5-xGa_x. Magnetization and Mössbauer measurements reveal two independent magnetic transitions in TbCo₃Ga₂ occuring around 20 and 200 K. There are strong indications that the lower transition involves the Co sublattice whereas the higher transition is connected with the Tb sublattice.
