    Poster: Partial substitution of calcium in Bi-Sr-Ca-Cu-O superconductor

  • Original language description

    Chemical substitutions may change structural and physical parameters in HTS. Substituents influence formation of Bi-2223 phase, pinning centers, intergrain connection and change hole carrier concentration. Bulk samples with partial substitution of calcium in Bi3.2Pb0.8Sr4Ca5-xMxCu7Oy by 5 B elements (M = V, Nb, Ta), x = 0 - 0.8 were prepared by solid state reaction in air. Resistivity and magnetic susceptibility measurements evaluated superconducting properties. Phase composition was checked by X-ray diffraction

    Částečná substituce vápníku v supravodiči Bi-Sr-Ca-Cu-O

  • Czech description

    Byly připraveny vzorky stechiometrického složení Bi3.2Pb0.8Sr4Ca5-xMxCu7Oy (M = V, Nb, Ta), x = 0 - 0.8. Jejich fázové složení bylo určeno pomocí RTG fázové analýzy a jejich transportní vlastnosti charakterizovány měřením teplotní závislosti elektrickéhoodporu a magnetické susceptibility.
