Research description

Superconducting materials, exhibiting outstanding current performances with few loses compared to conventional materials, have an enormous interest in the field of power applications. The Superconducting Group at ICMAB, collaborating with the EUSS Research Group, is intensively investigating the development of Coated Conductor tapes, based on high Tc YBCO superconducting thin films, fabricated by chemical-solution-deposition. This low-cost methodology would enable the industrial fabrication of km-length superconducting cables. Among other issues, we are investigating the vortex pinning mechanisms of different types of nanometric defects (naturally present, or artificially induced) embedded in the YBCO thin-film, in views of obtaining superconductors with yet higher critical current densities. The characterization of the YBCO thin-films is performed by combining different structural (X-ray diffraction, SEM, TEM…) and magnetic techniques (DC and AC magnetometry, resistivity, Hall imaging, XAS&XMCD etc).
