The Study of Superconducting Precursors in Bi/Pb Superconductors Fabricated using the Shock Wave and Sun Technologies by the Torsion Oscillation Magnetometry

August 4, 2022 Science and Technology 0

 Vibrating torsional Magnetometry was used to look into the possibility of raising the critical temperatures Tc of superconducting precursors in samples of the Bi-Pb-Sr-Ca-Cu-O superconducting system, which was created using hot shock wave consolidation technology (HSWC) and solar energy for melting and subsequent superfast quenching of the melt. The critical temperature Tc of a prospective superconducting precursor transition to the superconducting state rose from Tc = 107 K for the initial sample to Tc = 138 K by applying the HSWC technology for the synthesis of samples in the range of pressures from P=5 GPa up to P=12 GPa. A superconducting precursor with a Tc of 200 K was found in samples of the Bi-Pb-Sr-Ca-Cu-O superconducting system that were created utilising solar energy for the melting and rapid cooling of the melt. One can draw the conclusion that samples of this system contain high-temperature superconducting precursors with Tc 240 K by analysing the nature of the acquired dependences and comparing them to other data related to processes occurring close to the critical temperature Tc.
