Magnetic properties of hp13 type TiFe6Ge6 alloy

Abstract We have made magnetization measurements, Mossbauer spectroscopy and neutron diffraction on a hexagonal hp13 type TiFe 6 Ge 6 alloy; the 1a and 6i sites are entirely occupied by Ti and Fe, respectively. The alloy exhibits a simple antiferromagnetism with the magnetic moment of about 1 μ B /Fe atom at 12 K, the Neel temperature of 510 K and the paramagnetic Curie temperature of 70 K, and the internal field of 162 kOe at 295 K. This is in contrast with complicated magnetic properties of the isotypic alloys such as Fe 5 Mn 2 Ge 6 .
