ABSTRACT

Analysis of the excess conductivity of the Bi2Sr2ZnCu2Oх sample within the framework of the local pair model made it possible to determine the temperature dependences of the pseudogap △*(Т). For the Bi2Sr2ZnCu2Oх sample, the maximum value of the pseudogap is set.

Keywords: superconductivity, pseudoband, fluctuating conductivity.
