Inverse-Heusler合金Ti2Co1-xNixGa的磁性和半金属性
The magnetism and half-metallicity of inverse-Heusler Ti2Co1-xNixGa
摘要
Abstract
The half-metallic,magnetic and electronic properties were studied using density functional theory.The results show that the magnetic moment and lattice constants increase with the increase of x,which is slightly different from Slater Pauling rules owing to the direct hybridization between transition metal atoms and the influ-ence of sp electrons.The Fermi level of Ti2Co0.5Ni0.5Ga is just situated the middle of the minority-spin band gap,indicating the most stable half-metallic behavior.关键词
