关于Mn_3Al块体合金的电子结构计算

Research on the Electronic Structure Calculation of Mn_3Al Bulk Alloys

自旋电子学器件在航天、军事等高科技领域,甚至在智能家电、通讯等民用领域都有广泛的利用,因此它也引起了科学家们越来越多的关注。我们将对D03型Mn_3Al块体合金的电子结构和磁性利用理论模拟计算方法进行研究。根据理论计算发现Mn_3Al合金不仅具有100%的自旋极化率而且还有半金属特性的电子结构。关于合金磁性计算研究表明它是完全反铁磁性材料。Mn_3Al合金是一种半金属完全反铁磁材料,所以研究Mn_3Al合金对自旋电子学器件的设计具有重要意义。
