Fluctuation conductivity and microscopic granularity in bi-based high-temperature superconductors
(1997) [Artículo de periódico]Systematic conductivity measurements near Tc in granular (Bi,Pb)-Sr-Ca-Cu-O superconductors are presented, and focus is given on the interplay between thermal fluctuations and disorder at micro- and mesoscopic levels. ... -
Mechanical properties of highly oriented FeSe0.5Te0.5 superconductor
(2012) [Artículo de periódico]We have synthesized highly oriented samples of the superconducting compound FeSe0.5Te0.5 and investigated its mechanical properties. These samples were characterized by scanning electron microscopy (SEM) with energy-dispersive ... -
Separated suppression of the transverse and longitudinal Josephson flux mobility in a Bi/sub 1.6/Pb/sub 0.4/Sr/sub 2/Ca/sub 2/Cu/sub 3/O/sub y/ superconductor
(2001) [Artículo de periódico]We report on very detailed zero-field-cooling and field-cooling magnetization and magnetoresistance measurements in a polycrystalline Bi₁.₆Pb₀.₄Sr₂Ca₂Cu₃Oy superconductor. The results allow us to study the irreversibility ... -
Unconventional superconducting granularity of the Y/sub 1-x/Pr/sub x/Ba/sub 2/Cu/sub 3/O/sub 7-[delta]/ compound
(2006) [Artículo de periódico]We report on fluctuation magnetoconductivity and magnetic irreversibility of Y1−xPrxBa2Cu3O7− single crystals and a polycrystalline sample. Although our samples are all single phase orthorhombic and the single crystals ...
