Interplay of superconductivity and magnetism in superconductor/ferromagnetstructures - art. no. 054518

We study the influence of the proximity effect on several superconductor/fe rromagnet S/F layered structures. In the case of F/S/F sandwiches, we calcu late the dependence of the superconducting critical temperature as a functi on of the mutual orientation of ferromagnetic exchange fields of the outer layers. In the case of atomic-scale S/F superlattices, we analyze the prope rties of the superconducting phase for parallel or antiparallel orientation of magnetic moments of ferromagnetic layers. In both cases the superconduc ting pi -phase appears.
