Evolution of the excess conductivity in Y₁Ba₂Cu₃O₇-δ single crystals has been studied under stepwise oxygen removal by heat treatment. The concentration dependence of the coherence length along С axis εc(0) on the oxygen content has been obtained. The oxygen content reduction from δ ≤ 0.1 to δ ≈...
