The structural and magnetic properties of Mn{sub 5}(Sn{sub 1-x}Sb{sub x}){sub 3} compounds (x = 0-0.4) were investigated by means of X-ray diffraction and magnetization measurements. All samples crystallize in Ni{sub 2}In-type structure (P6{sub 3}/mmc) with the lattice parameters changing anisotropically with the increase of Sb concentration. Sb doping leads to the merging of the ferrimagnetic transition temperature T{sub c} and the re-entrant spin-glass transition temperature T{sub f}, indicating a direct transition from spin-glass state to paramagnetic state. The M(H) curve at 5 K evolves with x from a soft-magnet type to a linear-like shape. We proposed a basic explanation for the evolution of the magnetic properties in terms of crystal structure and magnetic interactions, which can be applied to other related compounds.
