We have made magnetization measurements, Mossbauer spectroscopy and neutron diffraction experiments on hexagonal hp13 type TFe6Ge6(T=Zr, Hf, Nb) alloys; the 1a and 6i sites are entirely occupied by T(=Zr, Hf, Nb) and Fe, respectively. The alloys exhibit a simple antiferromagnetism with the magnetic moment of about 1B/Fe atom at 295K. The Neel temperature TN, the paramagnetic Curie temperature p and the internal field Hin are as follows: TN=495K, p=70K and Hin=227K for T=Zr; TN=462K, p=62K and Hin=198K for T=Hf; TN=554K, p=71K and Hin=198K for T=Nb. This is in contrast with complicated magnetic properties of the isotypic alloys such as Fe5Mn2Ge6.
