Title: Real-space presentation of the magnetic anisotropy of metallic ferromagnets

A real-space representation of the uniaxial magnetic anisotropy (MA) of metallic ferromagnets is formulated using the full-orbital tight-binding model. By adopting a second-order perturbation for the spin-orbit interaction, numerical calculations of the uniaxial MA are performed for the L1{sub 0} FePt and Y{sub 2}Fe{sub 14}B compounds to evaluate the validity and applicability of the present method.
