Recent technological advances made it possible to create hybrid nano-structures with high quality ferromagnet/superconductor (F/S) interfaces. The F/S systems have been in focus of intensive experimental and theoretical studies because of both exciting fundamental problems and potential device applications. The physical properties of both F and S films will be strongly modified near the interface due to mutual proximity effect, for example, superconducting correlations penetrate into F and the spin polarization can extend into S. Main questions to be addressed in this talk will be the type and length scale of the induced superconducting correlations and spin relaxation length at the interface. Also, first experimental observation of superconducting switching effect depending on the mutual magnetization directions of F-layers in F/S/F trilayer system will be discussed.
