Application of ferromagnetic materials with properties set on nanolevel at resonant circuits creating of microwave (SHF) and THz (EHF) ranges

In this paper the available ferromagnetic materials, both the ones that are still under investigation and the ones that are applied in radioelectronics, including nanomagnetics, were analyzed. This analysis allows us to give an estimation of global trends in evolution of ferromagnetic usage in the new generation of SHF (microwave) and EHF devices. The paper accentuates the thin-film ferromagnetic media where the properties are set on nanolevel. These properties enable us to manage ferrostructures parameters and to apply the structures to resonant circuits for nonlinear parametric zonal systems (NPS), which are operating within current ultraharmonics in higher instability zones of electromagnetic oscillations. It is concluded that intense interest for the problem of realization of resonant structures based on NPS, operating on current ultraharmonics in higher instability zones of electromagnetic oscillations in SHF and EHF bands, lies within nanomaterials with several order parameters, especially multiferroics and carbon nanotubes.
