The Study of Superconducting Precursors in Bi/Pb Superconductors Fabricated using the Shock Wave and Sun Technologies by the Torsion Oscillation Magnetometry| Chapter 9 | Research Developments in Science and Technology Vol. 10

 

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.
