The first principle study of magnetic properties of Mn2WSn, Fe2YSn (Y=Ti, V), Co2YSn (Y=Ti, Zr, Hf, V, Mn) and Ni2YSn (Y=Ti, Zr, Hf, V, Mn) heusler alloys

The spin polarized electronic band structures, density of states (DOS) and magnetic properties of Mn2WSn, Fe2YSn (Y=Ti, V), Co2YSn (Y=Ti, Zr, Hf, V, Mn) and Ni2YSn (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 Mn2WSn and Ni2VSn show 100% spin polarization, Co2YSn (Y=Ti, Zr, Hf, Mn), Fe2YSn (Y=Ti, V), and Ni2MnSn exhibit metallic nature and Ni2YSn (Y=Ti, Zr, Hf) and Co2VSn show semi-conducting behavior.
