Proximity coupled half-metal ferromagnet/superconductor nanocomposites were fabricated and the superconducting transport properties of such hybrid nanostructured systems were investigated. The composition, structure, microstructure, morphology, valence states, dielectric, ferroelectric and magnetic properties of multifunctional hybrid systems obtained based on ferroelectric and magnetic nanomaterials have been studied. The fundamental laws governing the formation of magnetic, electrical, and dynamic properties of such hybrid systems have been established. It has been shown that the use of rotational deformation under high pressure leads to the creation of new multifunctional materials with a unique set of physical properties. Using infrared spectroscopy and muon spectroscopy, it was established that the magnetic order of Ba1 – xNaxFe2As2 single crystals has a mixed character of nonlocalized and localized magnetic moments. The evolution of Landau quantization of the spectrum of spinon pairs in a weak Mott dielectric La0.15Sm0.85MnO3+δ with a spinon Fermi surface is studied with increasing temperature and magnetic field strength. Analytical calculations and micromagnetic modeling have shown that in a homogeneous magnetic material it is possible to control the external electric field by refraction of the spin wave at the interface between regions with different external electric fields.
The scientific and practical value of the results obtained is extremely high. The research results expand and deepen the fundamental knowledge of the formation of specific magnetic, electrical, and dynamic properties of hybrid nanostructured materials, thanks to which their targeted practical use will be possible, which will contribute to the development of modern innovative technologies and the socio-economic potential of Ukraine.
