Flux Pinning Properties of REBCO coated conductors for High Field Magnets

초록

영어

From the viewpoint of high field application, the mechanical and critical current properties of recently developed REBa2Cu3Oy (RE123, RE: rare-earth) coated conductors are summarized. In addition, effective flux pinning mechanisms in RE123 are also introduced. As one of the examples for high field application, the upgrading of the 18 T cryogen-free superconducting magnet is shown. The large anisotropy of Jc is a problem at low temperature and high magnetic field. The nanorod is considered as the useful methods to improve the anisotropy of Jc, although its efficiency becomes small at low temperature.
