Pseudogap state in slightly doped by aluminium and praseodymium YBaCuO single crystals with a given topology of plane defects
In present work the conductivity in the basis plane of YBaCuO single crystals
slightly doped by Al and Pr with a pre-specified topology of twin boundaries
has been investigated. The excess conductivity for the analyzed samples shows
dependence like in wide
temperature range , where can be represents as mean field
temperature of superconducting transition. The temperature dependence of
pseudogap can be satisfactory described in terms of the BCS-BEC crossover
theoretical model.Comment: 3 pages, 2 figure
