    Non-isovalent metal substitution for bismuth, strontium, calcium, and copper in bi-based 2212 superconducting ceramics

    The aim of this paper is to investigate the influence of non-isovalent alkali (Li, Na, K, and Cs) substitution in Bi2Sr2CaCu2O8, in particular on its synthesis conditions and on their resistive and thermopower el...

    Magnetic alignment in 2212 Bi-based superconducting system: Part I. Magnetic orientation of Bi2Sr2Ca1−x(RE)xCu2O8−y [(RE) = Gd, Dy, Ho, Er] powder dispersed in epoxy resin at room temperature

    The magnetic anisotropy of rare-earth substituted 2212 materials (Bi2Sr2Ca0.8RE0.2Cu2Ox with RE = Gd, Dy, Ho, Er) is put into evidence. Superconducting powder dispersed in epoxy resin is oriented under an externa...

    Field dependence of the electrothermal conductivity of high-Tc superconductors

    The field dependence of the electrothermal conductivity P=S/ρ of high-Tc superconductors is calculated using a kinetic Boltzmann-like theory for either an s-wave or a d-wave gap parameter symmetry. The charge car...

    Magnetic alignment in 2212 Bi-based superconducting system: II. Bi2Sr2Ca1−xDyxCu2O8−yx = 0.2 glass recrystallized in 0.6 T magnetic field

    Starting from a glassy precursor, Bi2Sr2Ca1−xDyxCu2O8−y (for x = 0.2) was recrystallized under a 0.6 T magnetic field. After splat quenching, the samples were heated and sintered at different temperatures T1, the...
