Overview

abstract

• We investigate the magnetic arrangment of vicinal Fe surfaces by using a self-consistent real space tight-binding Hamiltonian. The presence of steps modifies locally the magnetic properties of the ideal flat surfaces. We point out the influence of the atomic environment and we found that, for Fe, the simple rule which relates a decrease of the local magnetic moment to an increase of the coordination number, is valid. The results are not very sensitive to the step length. Finally, arguments are given to explain the more subtle behavior of the surface atom. © 1992.
