The conditions of the existence of linear and transient operating regimes of microwave detectors based on SMNS are obtained. It is shown that the use of magnetic nanoscilators on the basis of SMNS for the development of ultrafast spectrum analyzers, promising for dual applications. The microwave characteristics of the composite magnetic nanostructures FM /islast film of metal and the advantages of using such systems in practice are shown. The research of own and stimulated processes in the surrounding layers of magnetic relaxation of the FM layer by Py, connected through a nonmagnetic layer with a synthetic ferromagnet (SFM), was carried out. The existence of a strong spin-flip effect in a non-collinear state of the structure, as well as modified effective conductivity in the antiparallel state, is similar to the effect of a giant magnetoresistance in SFM was obtained. The results allow to outline ways to develop and optimize spintronic elements of general and dual purpose devices. Product Description popup.authors Артемчук П.Ю. Боринський В.В. Кравець А.Ф.
