Superconducting tape having a flux pinning sites and Method for forming the same

摘要

PURPOSE: A superconductive wire and a manufacturing method thereof are provided to improve productivity by continuously forming a flux pinning site on a metal substrate. CONSTITUTION: A buffer layer(112) is formed on one side of a metal substrate(110). The buffer layer is comprised of a seed layer, a diffusion preventing layer, and a surface layer. The seed layer is contacted with the metal substrate. The diffusion prevention layer prevents the diffusion of the metal element from the metal substrate. The surface layer has a superconductive layer(140) and an affinity. A flux pining site(120) is formed with a pillar shape to cross the metal substrate and the buffer layer. The super conductive layer is formed on the outer side of the flux pinning site.
