Local quasiparticle density of states in ferromagnet/superconductor nanostructures -: art. no. 224514

We study the proximity effect in superconductor/ferromagnet (S/F) systems and propose a detailed theoretical description of the damped-oscillatory behavior of the quasiparticle local density of states in a ferromagnet. It is demonstrated that impurities play a very important role in determining the amplitude and the shape of spatial and energy dependance of the density of states. Bearing in mind the possible comparison with experiments, we investigate different types of S/F structures as well as temperature variation of the local density of states.
