Magnetic properties of Ni2In-type (Mn1− T)65Sn35 (T=Ti, Cr)

Abstract Magnetization measurements and partial neutron diffraction (ND) experiments have been performed on (Mn 1− x T x ) 65 Sn 35 ( T =Ti, Cr) systems. In Ti systems, the ferrimagnetic temperature range becomes narrower with increasing Ti concentration and disappeared at x =0.225 with direct transition between a paramagnetic state and a spin-glass state. In Cr systems, the σ – T curve shows a concave region at T t . The ND experiments for x =0.25 exhibit the presence of antiferromagnetic components lying in the basal plane and the magnetic structure is noncollinear type in T ⩽ T t .
