Abstract

We have made magnetization measurements, Mössbauer spectroscopy and neutron diffraction experiments on hexagonal hp13 type TFe6Ge6(T = Zr, Hf, Nb) alloys; the la 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 1 μB/Fe atom at 295 K. The Néel temperature TN, the paramagnetic Curie temperature θp and the internal field Hin are as follows: TN =495K, θp=70 K and Hin= 227 K for T = Zr; TN = 462 K, θp = 62 K and Hin = 198 K for T = Hf; TN = 554 K, θp = 71 K and Hin = 198 K for T = Nb. This is in contrast with complicated magnetic properties of the isotypic alloys such as Fe5Mn2Ge6.
