摘要：

The iron and manganese germanides RT6Ge6 (R=Sc, Y, Nd, Sm, Gd-Lu; T=Mn, Fe) have been investigated by X-ray diffraction and susceptibility measurements in the temperature range 90-900 K. They crystallize in the known HfFe6Ge6, YCo6Ge6, TbFe6Sn6 or HoFe6Sn6 type of structure except GdFe6Ge6 which is of a new type. All the compounds are anti-ferromagnetic except the RMn6Ge6 (R=Nd, Sm, Gd) compounds which behave ferrimagnetically. Weak coercive fields (down to 1 kOe) are measured in RMn6Ge6 (R=Nd, Sm).
