In this thesis, we will discuss the implications of the proximity effect on superconductor/ferromagnet (SF) nanostructures. We will describe how to calculate a fully self-consistent pair amplitude from the Bogoliubov-de Gennes equations. It is only through a fully self-consistent calculation that we can properly describe the proximity effect. We then give three examples of systems for which the proximity effect plays an important role in the macroscopic properties: thermodynamics in SFS multilayers, induced triplet states in s-wave superconductors, and transport properties of SF bilayers. |
