N2 - The fcc Co/Cu(001) system is investigated using the full potential linearized augmented plane wave method. Through the atomic force approach, large multilayer relaxations (6.5%, 5.3%, and 2.8%) are found between the adjacent Cu layers, which reduces the total energy by 128 meV. The spin and orbital magnetic moments for Co atoms are 1.79 and 0.12 μB, respectively. At the interfacial Cu site, we found a sizable induced magnetic moment, 0.05 μB, which can be split into d (0.074 μB) and s,p(0.024 μB) contributions. Interestingly, the spin polarization of d and s,p states can be detected separately through the magnetic circular dichroism at the L and K edges, for which the calculated results agree very well with experiments.
