The development of technology of HTSC-materials with their outstanding possibility to conduct high-dense superconducting currents without dissipation has led to the appearance of commercial superconducting cables with work temperature of liquid nitrogen and the large-long HTSC film materials. When anyone tries to increase the current capability of copper oxides, he will be met by two opposite problems: on the one hand, it is needed to create the material, which has the high perfect crystallinity close to the single crystal; on the other hand, to ensure high-dense superconducting currents in a specimen, special structure defects must be presented enough for effective pinning force of the Abrikosov vortex lines. In our work, we analyze the technology of preparing of traditional polycrystalline HTSC-materials, which includes their thermomechanical treatment by using the high-density pulsed plasma. These results are compared with the untraditional technology of HTSC’s preparing on the base of metal-organic chemical vapour deposition of thin films. The conclusion about the high perspectiveness of the untraditional technology of HTSC’s preparing based on synthesis of the copper-oxide superconducting thin films is made.
Keywords: HTSC-materials, pulsed plasma, MOCVD technology.
