  • Fluctuation conductivity due to the preformed local pairs 
    Domański, T.; Barańska, M.; Solovjov, A.L. (Физика низких температур, 2016)
    We investigated the properties of a system where the itinerant electrons coexist and interact with the preformed local pairs. Using the nonperturbative continuous unitary transformation technique we show that Andreev-type ...
  • Fluctuation conductivity in Y-Ba-Cu-O films with artificially produced defects 
    Solovjov, A.L. (Физика низких температур, 2002)
    The fluctuation-induced conductivity (paraconductivity) measured in YBa₂Cu₃O₇₋d (YBCO) films grown on 10° miscut SrTiO₃ (001) substrates is analyzed using various theoretical models describing weak fluctuations in high-Tc ...
  • Hall effect studies in YBCO films 
    Solovjov, A.L. (Физика низких температур, 1998)
    The longitudinal, rhoxx(T), transverse, rhoxy(T), and Hall, rhoH(T) resistivities have been measured for YBa₂Cu₃Ox (YBCO) films, showing positive resistivity buckling and those with usual linear rhoxx(T) dependence. In the ...
  • Possibility of local pair existence in optimally doped SmFeAsO₁₋х in pseudogap regime 
    Solovjov, A.L.; Svetlov, V.N.; Stepanov, V.B.; Sidorov, S.L.; Tarenkov, V.Yu.; D’yachenko, A.I.; Agafonov, A.B. (Физика низких температур, 2011)
    We report the analysis of pseudogap Δ* derived from resistivity experiments in FeAs-based superconductor SmFeAsO₀.₈₅, having a critical temperature Tc=55 K. Rather specific dependence Δ*(T) with two representative temperatures ...
  • Pseudogap and Local Pairs in High-Tc Superconductors 
    Solovjov, A.L.; Tkachenko, M.A. (Металлофизика и новейшие технологии, 2013)
    The temperature (T) dependence of pseudogap (PG) Δ*(T) is calculated for Bi2201 within the local pair (LP) model [1, 2]. The model is based on analysis of the excess conductivity derived from resistivity experiments in ...
