The magnet-scientific method has been adopted for fabricate grain oriented materials in these 20 years using superconducting magnets with large room temperature bore. High magnetic field up to 10 T enabled us to control grain orientation of paramagnetic materials if they have magnetization anisotropy. In the case of cuprate superconductors, the magnetization easy axis is determined by...
Conventionally the fabrication of superconducting thin films is carried out by tedious processes and requires expensive equipment. Here we report the growth of YBa2Cu3O7-x (YBCO) thin films on SrTiO3 substrates by the low-cost chemical solution deposition technique [1]. The preparation includes the precipitation of yttrium, barium and copper acetates in oxalic acid; and directly dripping onto...
Maximizing critical current density (Jc) and minimizing flux creep in high temperature superconductors (HTS) is critical for their inclusion in accelerator magnets where both high magnitude and high stability magnetic fields are required. In YBa2Cu3O7-x (YBCO) thin films, critical current density can be enhanced by either the addition of many shallow pinning centers or the addition of fewer,...
Different methods of flux pinning are being tested world-wide to enhance critical currents (Ics) of high temperature superconductor YBa2Cu3O7-x (YBCO) coated conductors exposed to high magnetic fields. Magnetic materials are interesting to consider as flux pinning additions because of their potential for very strong pinning strength. To our knowledge, there have been limited demonstrations...
