Abstract
We theoretically study the proximity effect in ferromagnet–superconductor trilayer in the F\(_1\)F\(_2\)S design. Electron–electron pairing interaction in F layers is taken into account. The boundary value problem is considered in the frame of Usadel equations. The conditions of the solitary superconductivity appearance in F\(_1\)F\(_2\)S system are theoretically investigated taking into account of arbitrary transparencies of interfaces. The experimental observation of this effect and its spin-valve application are discussed.
