Found out and grounded a transition from hysteresis volt-ampere descriptions below 4.2 K to anhysteretic - higher 4.2 K. The influence of microwave radiation on the transport descriptions of Nb/Al-AlOx-Nb of hetaeracontacts is investigated. The effective method of receipt of epitaxial tapes of іtriy-barium cuprate of YBCO is developed on linings of GaN/sapphire. It is rotined that, in quality a buffer layer, YBCO of tape allows to get the use of the thin layer of MGO in thick 300 нм with a zero resistance at 80 K. These tapes were utillized farther for creation of ionic irradiation of anhysteretic jozefsonic hetaerastructures a method. Investigational possibility of generation of electromagnetic signals of free-form is by the chainlet of jozefsonic contacts on the basis of іtriy-barium cuprate. It is rotined that the most effective method of analysis of nondeterministic signal of ultrahigh-frequency is Gilbert-spectroscopy, based on frequency selective detection of electromagnetic radiation by superconductive jozefsonic transitions. By the developed method of analysis of base descriptions of nondeterministic signals of ultrahigh-frequency the spectrums of absorption of metanol and acetone were probed. Efficiency of the offered hike is shown for an exposure chemically of hazardous substances. Product Description popup.authors Москаленко М.А. Новіков Є.І. Пустильнік О.Д.
