Studied has been the effect of oxygen deficiency as well as of a low (up to 5 %) Al and Pr doping on conductivity in the basis plane of the ReBa₂Cu₃O₇₋δ (Re=Y, Ho) HTSC single crystals. The excess conductivity Δσ(T) of the studied samples has been found to show an exponential character in a wide tem...
