Method for fabricating an yttrium-based high temperature superconducting tape

摘要

A polycrystalline silver member is stuck on a given long member made of Hastelloy material or stainless steel material, to make a long base material. Then, an yttrium-based high temperature superconducting film is fabricated in the long base material by a CVD method with applying a magnetic field of preferable 2T or over. Thereby, an yttrium-based high temperature superconducting tape can be provided which can maintain the superconductivity under a higher magnetic field environment.
