Abstract
A detailed study of the electronic structure of the c(2×2)-MnCu/Cu(0 0 1) surface alloy at the Fermi level is presented. We show that the complex topology of the two-dimensional momentum distribution of the electrons is due to the sum of two effects: the projection of the bulk Fermi surface onto the (2×2) plane, and the presence of new electronic states induced by the minority spin band of Mn. The crucial role of the surface potential in the intensity and dispersion of the states is discussed.
