Abstract
The magnetic anisotropy energy of Ni-n/Cu(100) is calculated in terms of th e spin-polarized fully relativistic Korringa-Kohn-Rostoker method including surface relaxation by using 2D structure constants originally described fo r low-energy electron diffraction calculations. Investigating different rel axations, an explanation for the reorientation transition from in-plane to perpendicular can be given. For a relaxation of -5.5% (c/a = 0.945) this re orientation occurs at about seven layers of Ni and yields second order term s to the magnetic anisotropy energy that are in excellent agreement with ex periment.
