Magnetocrystalline anisotropy of Co3Si (001) films from first principles

Magnetocrystalline anisotropy of Co3Si (001) films from first principles

The creation and control of magnetocrystalline anisotropy in bulk and nanostructured magnetic materials remain a continuing challenge, and density functional theory assists the experimental research in developing new high-anisotropy magnetic materials. Co3Si, which crystallizes in the hexagonal CdMg...
