Spin polarization of Cr/V vicinal structures

The magnetism is investigated for chromium (Cr) overlayers adsorbed on vanadium (V) vicinal substrates. The calculations of the magnetic moments are carried out by the real-space self-consistent tight-binding (TB) recursion method in the Hartree–Fock approximation. These structures exhibit the largest magnetic moment at the edge atom and the least at the kink. Appreciable magnetic moments are induced on V sublayers antiferromagnetically coupled with the surface moments where this coupling is frustrated at kink atoms. The net magnetization increases as a function of the step length and persists for few layers below the surface.
