摘要

We used a surface-dedicated first-principles method to calculate the electronic structure in Co/Ni(111) overlayers with a Co thickness varying between 1 and 5 monoiayers. We describe the majority and minority spin surface states, resonances, and quantum-well states and their dispersion, the energy and the number of these states depending on the Co-layer thickness. The difference between the total density of states and spin polarization of the different overlayers is found to be more important above the Fermi level. These results could be useful to analyze the surface-state spectra (spin-resolved direct and inverse photoemission, scanning tunneling spectroscopy) recorded in situ during the growth of Ni/Co multilayers for spintronic and nanomagnetism applications.
