Interelectronic interaction in dirty FS trilayers: A manifestation of "hidden" superconductivity

Abstract

© 2014 Elsevier B.V. The properties of the ferromagnet/superconductor (FS) system are theoretically studied. Electron-electron pairing interaction in F layers is taken into account. The boundary value problem for the Usadel-like equations is considered in the case of so-called "dirty" limit. It is shown that both asymmetry and interelectronic interaction essentially influence on the critical properties of the F<inf>1</inf>SF<inf>2</inf> trilayer. The appearance of the solitary superconductivity is predicted for this asymmetrical trilayer.
