Substitutions in Bi-based superconductors

Popis výsledku v původním jazyce

Discovery of superconductivity in bismuth based cuprates raised a new wave of interest in high temperature superconductivity and much effort has been applied towards improvement of their superconducting properties. Modification of such properties can beachieved by doping or substitution of the present elements by atoms of other elements. They can create new pinning centres by forming some additional non-superconducting phase or modify charge carriers density by changing either copper oxidation state orlattice parameters and thus influence transport properties of the superconductor. New atoms may also form some low melting phase which then eases formation of the superconducting phase.Three superconducting phases with general formula Bi2Sr2Can-1CunO2n+4 were identified in the system Bi-Sr-Ca-Cu-O. Critical temperature Tc increases with increasing n up to 110 K for n = 3 (phase BSCCO 2223). In this work we studied the influenece of Li and Cs addition on formation and properties of the p
