SubTHz and THz-bands Radioelectronic Devices Creation Working in Low Temperatures Conditions of Near Space and Arctic/Antarctic Regions

Resources of magnetophotonic nanostructures, able to apply in the low temperature environment, are considered. Investigations implemented by authors have demonstrated that, in association with applied photonic or magnetic substances, their nanocrystal structure and disposition (1 D, 2D or 3D structure), application technology, etc., it is very likely that the ferromagnetic nanostructures can be making, that are able to work steady in the extremal conditions of Arctic and Antarctic regions, Near Space, and Solar System planets - at presence of low temperatures and strong influence of ionized radiation. Concentration of impurities, their distribution within magnetophotonic nanocrystal structure and many other factors are very important at subTHz and THz devices of new generation creation. Ferromagnetic and nanophotonic structures opportunities joint application is able to unclose the wide potential for magnetophotonic nanostructures making, in which the ferromagnetics will found the wide application: ferrite-garnets, orthoferrites, various spinel materials and metal amorphous thin films.
