Information × Registration Number 0211U009571, 0109U001441 , R & D reports Title Dissipative transport and ordering of vortex matter under presence of direct and alternative currents popup.stage_title Head Vovk Ruslan Volodymyrovych, Registration Date 30-12-2011 Organization Kharkov National University named after V.N. Karazin popup.description2 The objects of experimental research - perfect single crystals of high-temperature superconductor YBaCuO and epitaxial films of niobium with artificially created on the film surface topography of the "washboard." Purpose - to study the characteristics of electric transport in the HT superconductors of the 1-2-3 system, with varying degrees of deviation from stoichiometry and the effect of stoichiometry on the pseudogap regime and the fluctuation conductivity, and the dynamics of Abrikosov vortices in fabricated and tested samples of epitaxial niobium films with an artificially created surface "washboard."relief of the film . The method of research - the analysis of electrotransport properties of HTSC single crystals and niobium films with different orientations the direction of the relief relative to the transport current and magnetic field. Specific features of the pseudogap state of single crystals YBaCuO with varying degrees of doping impurities and oxygen as well as the theoretical justification of the effects associated with microwave absorption capacity in the presence of direct current in II-type superconductors. The research results can be used in further work to create models of superconducting state in HTS and the critical parameters of the samples in terms of their practical use in high-frequency devices.
