Inverse Proximity Effect in FSF Heterostructures — Christian Wagner¹, Roland Grein¹, Matthias Eschrig^1,2, and •Gerd Schön¹ — ¹Institut für Theoretische Festkörperphysik and DFG Center for Functional Nanostructures (CFN), Karlsruhe Institute of Technology, D-76128 Karlsruhe, Germany. — ²Fachbereich Physik, Universität Konstanz

We employ the quasiclassical theory of superconductivity to study the inverse proximity effect in FSF trilayer structures, where F is a strongly spin-polarized ferromagnet and S a singlet superconductor. In particular, we focus on effects induced by spin-dependent scattering phases at the S/F-interfaces. The resulting triplet pairing component will lead to a suppression of the superconducting gap. This enables us to investigate the influence of the relative magnetization orientation of the two ferromagnetic layers on the superconducting transition temperature.
