The hexagonal Ni2In (B82) type Mn7Sn 4 has a collinear ferrimagnetic structure. The intermetallic compound (Mn1-xFex)65Sn35 systems crystallize in the Ni2In type in the range of 0 ≤ x ≤ 0.4. The present paper describes the results of investigations of the crystal and magnetic properties of the Ni2In type (Mn1-x Fe x)65Sn35 compounds with X-ray and neutron diffraction, as well as magneto metric methods. The neutron diffraction study at room temperature for some samples revealed that the Fe atoms occupy only 2(d) site for x = 0.1 and 2(a), 2(d) site for > 0.1. The neutron diffraction study at T = 10 K for x = 0.25 revealed the ferromagnetic structure. The inverse susceptibility χ-1-T curve shows a bend in the lower x suggesting the ferrimagnetic nature but nearly linear in the higher x suggesting the ferromagnetic nature.
