It is shown that the exchange shift in such oxides is due to the additional deformation of the inclination angle for the iron magnetic sublattice in a weak magnetic field. A new approach to the spectroscopy of electron-boson interaction in strongly coupled superconductors, based on the resistive switching effect in binary oxides, has been proposed and experimentally implemented. It allows to modify transparency of a nanoscale oxide layer between an injector and the investigated superconductor in a controllable way. The proposed technique was tested on two superconductors - niobium and magnesium diboride. It is proposed a discrete model of the memristive behavior of hybrid structures, capable to combine mechanisms different from a physical point of view and, at least, qualitatively predicte dependence of the memristive system resistance on the electric field. Proximity effect in a normal metal – superconductor hybrid structure is theoretically considered; temperature dependences of a superconducting gap induced in a normal metal, as well as its spectral density of states are calculated. A theoretical model of the charge transport in a heterostructure based on a two-gap superconductor coated with a nanoscale normal-metal film is developed. It is shown that differential conductivity measurements for such structures can provide unambiguous proof of the presence of two (or more) energy gaps in a superconductor, in contrast to the trivial effect of spatial inhomogeneity.
