Four-layered ferromagnet-superconductor nanostructures: critical temperatures and control devices (in Russian)
Abstract
Four-layered FM/S/FM'/S' systems consisting of rather dirty superconducting (S) and ferromagnetic (FM) metals are sequentially considered on the basis of the original proximity effect theory early proposed for the artificial ferromagnetic metal/superconductor (FM/S) nanostructures. The dependences of critical temperatures on thicknesses of layers in a wide range of parameters are investigated. It is proved, this system can have different critical temperatures for layers S and S'. It is shown, that four-layered systems are the most perspective candidate for use in superconducting spin electronics and can serve element base for creation of the microelectronic equipment of essentially new type combining advantages of superconducting and magnetic record channels in one sample.
