Abstract

The influence of KClO3 addition on the AC complex susceptibility (χac) and micro structural morphology of YBCO HTSC with nominal composition Y(1-0.2x)Ba(2-0.2x)KxCu3O y (x = 0 ÷ 0.40) were investigated. χac was recorded as a function of temperature and of the concentration of KClO3 in various AC magnetic fields up to 19 Oe. The data were analyzed using the relation h = a(1 - Tm/Tc)n. The results obtained showed that the presence of K- and Cl-containing impurities on the grain boundaries change the intergranular coupling and, within certain concentration limits, improves the superconducting parameters.
