Abstract

The temperature dependences of normalized pseudogap and excess current of cuprate high temperature superconductors YBa₂Cu₃O_6,85 and Bi_1,6Pb_0,4Sr_1,8Ca_2,2Cu₃O₁₀ were obtained in the framework of modified model of local pairs with the Monte-Carlo method. It was shown at the temperature T_pair = 130K for YBa₂Cu₃O_6,85 and T_pair = 180 K for Bi_1,6Pb_0,4Sr_1,8Ca_2,2Cu₃O₁₀ the maximum pseudogap width coincides with the excess current deviation from linear dependence.
