Influence of a boron oxide admixture on the superconducting properties of the bismuth-containing 2212 phase
The effect of an admixture of boron oxide B 2 O 3 on the superconducting properties of the bismuth-containing 2212 phase is investigated. It is found that boron doping improves the superconducting transition characteristics of Bi 2 Sr 2 Ca 1 Cu 2 O y and Bi 1.8 Pb 0.2 Sr 2 Ca 1 Cu 2 O y samples slow...
