Improvement of critical current density in Sb-doped HgBa2Ca2Cu3O8+delta superconductor prepared by Hg vapour diffusion process

Abstract:

Antimony-doped Hg-1223 superconductors have been synthesised from the reaction of a Sb-doped precursor with elemental Hg vapour released from a reactant in sealed silica tubes (the Hg vapour diffusion process). The Hg vapour pressure can be controlled by a small addition of Se in the reactant bars. The phase purity and micro structure of the material have been characterised by XRD and SEM and the superconducing properties measured by electrical resistance and AC susceptibility. High quality s...
