Abstract

We performed first-principle calculations to investigate the structural, optoelectronic, and magnetic properties of Co2MnSi Heusler alloys using density functional theory based on full- potential linearized augmented plane wave (FP-LAPW) method. We employed three approaches LSDA, LSDA+U and Hybrid on-site exact exchange, where the Hubbard correction U is calculated by constraint LDA for Co and Mn. Our results showed the half- metallicity character with integral magnetic moment of 5μB, which agrees with the Slater- Pauling rule. Our findings suggest that these materials are potential candidates for manufacturing Spintronic devices and Nanotechnology.
