A detailed study of the electronic structure of the c(2x2)-MnCu/Cu(001) 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 (2x2) plane, and the presence of new electronic states induced by the minority spin band of Mn. The crucial...
The surface electronic configuration of Pt 3 Mn(111) and layered (2x2) Pt/Pt 3 Mn(111) compounds within a parametrized tight-binding scheme is calculated by means of the Surface Green Function Matching method. The effects of the spin-orbit coupling within the central cell approach are studied in detail, concerning both the layer density of states and the atomic magnetic moments. A...
