We report the first-principle calculations of the Co₂VSn and V₂CoSn Heusler alloys in L2₁ phase. These alloys are found to be stable in ferromagnetic states. The bulk modulus decreases after the interchanging of the Co-V element positions in Co₂VSn alloy. In comparison with half-metallic nature of Co₂VSn, V₂CoSn Heusler alloy showed the metallic character. Moreover, after the swapping of X to Y positions in Co₂VSn Heusler alloy, the enhanced magnetic moment (5.834 μ_B/f.u.) was obtained with respect to magnetic moment (3.021 μ_B/f.u.) of Co₂VSn alloy.

XY交换紊乱导致Co 2 VSn Heusler合金的半金属破坏

我们报告了L2 ₁相中Co ₂ VSn和V ₂ CoSn Heusler合金的第一性原理计算。发现这些合金在铁磁状态下是稳定的。Co ₂ VSn合金中的Co-V元素位置互换后，体积模量降低。与Co ₂ VSn的半金属性质相比，V ₂ CoSn Heusler合金表现出金属特性。此外，X的钴对换到Y位置后₂ VSN哈斯勒合金，增强的磁矩（5.834 μ_乙物相对于磁矩（3.021获得/福）μ_乙的Co / FU）₂ VSN合金。
