Spin-Other-Orbit Interaction and Magnetocrystalline Anisotropy



Mark D. Stiles, S Halilov, R Hyman, A Zangwill


We report the effect of the two-body, spin-other-orbit interaction on the magnetocrystalline anisotropy energy of the 3d transition metals. The relevant energy differences were computed for bcc Fe, fcc Ni, and hcp Co using the linearized augmented plane wave method to solve the Kohn-Sham equations in the local spin-density approximation. The spin-other-orbit interaction was incorporated at the level of the Hartree approximation. Special care was taken to guarantee the correctness of our numerical procedures. We find that the spin-other-orbit interaction does indeed change the anisotropy energy, but the effect is too small to account for the disagreement with experiment found in previous calculations for all three elements.
