ABSTRACT

The experimentally discovered minima in the ρ(T) dependence, within the framework of classical theories of superconducting fluctuations, in our opinion, directly indicates the possibility of the formation of fluctuation Cooper pairs in the studied CdBa2Cu3O6 SC sample at T > Tmin >> Tc. This allows us to say that in CdBa2Cu3O6 an attempt at a superconductive phase transition is observed at Tmin. For the first time, based on experimental data on conductivity, the formation of a pseudogap in CdBa2Cu3O6 with Tc = 86.6 K was confirmed and its temperature dependence was assessed.

Keywords: superconductivity, fluctuation conductivity, resistivity, critical temperature.
