The spin polarized electronic band structures, density of states (DOS) and magnetic properties of Mn 2 WSn, Fe 2 YSn (Y=Ti, V), Co 2 YSn (Y=Ti, Zr, Hf, V, Mn) and Ni 2 YSn (Y=Ti, Zr, Hf, V, Mn) huesler compounds are reported. The calculations are performed by using full-potential linearized augmented plane wave method (FP-LAPW) within density functional theory. The magnetic trend in these compounds is studied using values of magnetic moments, exchange interaction and calculated band gap. The results reveal that Mn 2 WSn and Ni 2 VSn show 100% spin polarization, Co 2 YSn (Y=Ti, Zr, Hf, Mn), Fe 2 YSn (Y=Ti, V), and Ni 2 MnSn exhibit metallic nature and Ni 2 YSn (Y=Ti, Zr, Hf) and Co 2 VSn show semi-conducting behavior.
