Preparation and characterization of mercury (Hg) doped BSCCO superconductors
Since the discovery of superconductivity by Maeda et al., in the Bismuth-Strontium-Calcium-Copper-Oxide (BSCCO) system, extensive studies on the preparation and characterization of this cuprate system of superconductors have been conducted. Most fabrication processes utilized ceramic methodologies. The most widely used technique is the solid-state reaction method. Numerous studies have been conducted on doping (by either addition or substitution) Lead (Pb) into the Bimuth (Bi) site of the said system. Several researches on the addition of Antimony and Tin in the Bi-Pb-Sr-Ca-Cu-O system have also been conducted.
In this paper, we report the preparation and characterization of Mercury-doped Bi-Sr-Ca-Cu-Oxide (BSCCO) superconductors from a parent structure of CaSr0.1CuO7.
