Influence of KClO{sub 3} addition on the magnetic properties and microstructural morphology of Y{sub 1{minus}0.2x}Ba{sub 2{minus}0.2x}K{sub x}Cu{sub 3}O{sub y} (x = 0{divided{underscore}by}0.40) polycrystalline HTSC
The influence of KClO{sub 3} addition on the AC complex susceptibility ({chi}{sub ac}) and microstructural morphology of YBCO HTSC with nominal composition Y{sub (1{minus}0.2x)}Ba{sub (2{minus}0.2x)}K{sub x}Cu{sub 3}O{sub y}(x = 0 {divided{underscore}by} 0.40) were investigated. {chi}{sub ac} was recorded as a function of temperature and of the concentration of KClO{sub 3} in various AC magnetic fields up to 19 Oe. The data were analyzed using the relation h = a(1 {minus} T{sub m}/{Tc}){sup n}. The results obtained showed that the presence of K- and Cl-containing impurities on the grain boundaries change the integranular coupling and, within certain concentration limits, improves the superconducting parameters.
