We use a tight-binding Hubbard Hamiltonian solved in the unrestricted Hartree-Fock approximation to obtain the bandstructure. Once selfconsistency is achieved we perform one further diagonalization including the spin-orbit interaction term. By changing the spin quantization axis we obtain the band energy and the magnetic moment for different configurations. We analize the effect of the spin-orbit coupling on the band structure and its relationship with the magnetic anisotropy energy.
