Fabrication of superconductors by laser zone fusion comprises electrification during the fibre growth for single and multi filaments production

摘要

The fabrication of superconductors by laser zone fusion consists of application of electric current during growth of the fibres of Bi-Sr-Ca-Cu-O system superconductors. The microstructure obtained significantly increases the critical current density of the fibres, with production of single- and multi-filament devices by optical division of the laser beam.
