Rezumat

A heterostructure comprising several ferromagnetic (F) and superconducting (S) layers acquires functionality of guiding the superconducting properties of a system applying external magnetic fields. It is superconducting spin-valve effect. In the talk, several designs of the superconducting spin-valves are considered, the existing experimental data for the weak and strong ferromagnetic materials are analyzed; the role of the domain structure of the ferromagnet and the scattering of electrons with spin flip on the S-F interfaces on the magnitude of the valve effect is described. The effect of the triplet pairing components on the critical temperature of S-F heterostructures is analyzed. The theoretical as well as experimental works in the field are reviewed.
