標題: | First-principles investigations of the magnetocrystalline anisotropy in strained Co-substituted magnetite (CoFe2O4) | 作者: | GUANG-YU GUO | 關鍵字: | Electronic structure; Ferrite; Magnetic anisotropy energy | 公開日期: | 2002 | 卷: | 239 | 期: | 1-3 | 起(迄)頁: | 88-90 | 來源出版物: | Journal of Magnetism and Magnetic Materials | 摘要: | The magnetocrystalline anisotropy energy of CoFe2O4 under uniaxial strain along [0 0 1] direction has been studied by using the linear muffin-tin orbital method within the density functional theory. The calculated uniaxial anisotropy constant Kout is positive for extensive in-plane (0 0 1) strains and is negative for compressive in-plane strains. The positive value of Kout indicates that a CoFe2O4 film under an extensive in-plane strain would show the out-of-plane [0 0 1] magnetization. © 2002 Elsevier Science B.V. All rights reserved. |
